305 TPI to 335 TPI........
I've read from that Project Silver Streak from Gr8rides.com has a 305 with a 335 kit I've been thinking on getting this engine and the kit, It's been rated at 270 hp/325 on torque I think those are very good numbers,,...and please no trashing the 305....I'm on a budget....and need a new power plant to put in without spending too much money on computer probs,and what not.......How much would this 335 cost about......????

About $800 plus shipping for the rotating parts kit with 5.7 rods and hypereutectic pistons, externally balanced flexplate and harmonic balancer from Powerhouse. Plus boring the cylinders .030" over and grinding the pan rails for rod clearance. Should also include tanking the block and replacing the cam bearings and freeze plugs. Probably about $250-300 in machine shop costs there. You're upgrading the cam while you're at it, of course, so there's a couple hundred more. Timing set, $60, gaskets & seals $70. Oil pump, $25.
Hey, you're doing this right, correct? Then:
World Products 305 S/R Torquers heads ~$650 assembled & shipped from Competition Products (use 350 head gaskets). Hooker 2055 headers & y-pipe, 3" cat & cat-back from Summit, ~$650.
Subframe connectors and poly bushings to take the extra power.
But the computer will be fine.

Hey Cloud I'm doing the same build, the Powerhouse catalog lists 2 prices one is for the 2 piece seal block, $599+$199 for balance (new flexplate and balancer), for the one piece seal block it's $888 that includes balancing, new flex plate (late model style), new balancer, and gasket set for F.I or carb. The build up should start as soon as I get the block back from the machine shop 
Btw the email address for Powerplant is powerplant@lightspeed.com send them your address and tell them u want a catalog

I'm sure you guys have heard this before but I can't help myself.... "why?"
That just sounds like an awful lot of money to spend on polishing a turd.
The 305 is a good motor, I have one too. But for the SAME PRICE of building up (boring/Stroking) your 305 you could get a 350 block and use most of your parts from the 305 on it. Also, a 305 has to work harder to make the same amount of power than a 350 does.
Also with the 350 you have a good foundation to build a real nice powerplant.. Like say, a 383??? There's a stroker for ya!
Don't sell yourself short guys... Sure it's cool to do this to a 305, but is it worth it??? You even said yourself you are on a tight budget. Get the most bang for the buck!

Well Brian not to be rude or anything, but I could ask u the same question. Why an RS and not a Z with a 350? I have my own reasons for doing a 305 stroker,
1. Curiosity, how much power can this 305 make? Super Chevy got 302hp and 387 tq on theirs.
2. I'm not looking to be king of the drag strip, I'm simply looking for a nice driver, with some get up and go
3. 350/383's have been done to death
4. I have a 305 block and I have really bad luck with junkyard parts (the last 2 350's I got were both cracked) so for a new block it's an additional $550
5. Should I ever decide to do a 383 in it all of the parts (except pistons) will interchange with a 350
These are just a few of the reasons I decided to try a 305 stroker, there are others too, And should u see a blue Iroc with the tag "oldbluz" driven by an older guy (me) race me and see how it turned out
cause I'm about 50 miles south of u I hope to have at least the engine and tranny done by the Last Run so I can enter it

we are doing the same stroker kit for a friend of mine, using the powerhouse 335 kit. its a 92Z tpi305, sweet, sweet car. the guy is putting everything on it, slp runners, edelbrock upper and lower, throttle body, all sorts of stuff, he's picked out some roller cam from slp also. i am in the process of notching the 305 block, if you do the stroker, get out the grinder cause damn the thing doesnt fit in the stock block.

It just seems pointless to dump cash into an INFERIOR motor. To get anything higher than 280 or so horsepower you'll need to run a brutal cam. Which will make your car less street friendly.
Go ahead and dump tons of cash into your 305. If you're lucky you'll be able to run with stock LT1s.. Meanwhile I'll drop in a 355 that I found for $700 that will put my car into low 13s.

Did anyone read my first post I said no trashing the 305 dah......
anyhow I need to get a new block, my heads and all the rest will probably be added from the old engine.....which is a 305 TPI so the TPI will just slide right on top....I'm not getting a new distributer or ignition or anything like that I'm just gonna get the kit and the new block so how much will that cost I'm thinking about $1500 just for parts including (305 Block,Powerhouse 335 kit,and adding parts that need to be added from the old or replaced from the old) how much would you guys be expecting???

Actually I'm on a budget.... but I spoke with the machine shop about it and they said that this would be cheaper then getting a 350 only for the sole fact that the have to reprogram the computer which is very tedious for them to do....

No reprogram??? Without a reprogram your stroker will not see it's full potential. And it will probably run like crap.
What's going to happen a year from now when your 335 isn't giving you the amount of power you need? Back to square one.

I'm not trying to be an *** or anything. I'd personally love to have a car with a 335 stroker. But it is just not worth the money spent.
And the 335 doesn't put that much power out to begin with.
And the 335 doesn't put that much power out to begin with.
Well I called a local shop and they gave me an price and they said they'd do it for only $2600......I think that's a better price then having to reprogram,drop in a $3000 350 engine plus labor that's like $700 in labor with the reprogram.....so that's almost $1000 more than I really wanna spend.....My car has 115000 miles on it sooner or later my tranny's gonna go, my rearend is gonna go, and I won't have the money to fix these.... so putting in a new 335 this year for $2600 and spending $1400 next year for new 700R4 tranny, and about $2000 next year for new rear end....I think it is economical to save $1000 for the tranny next year.....

Come next year, when you have to replace your tranny.. Will you still be happy with the 280-300 hp that your 335 is making?
Speed is an addiction... You get something fast then you want to go faster and faster..
I personally could not see myself spending 2,600 on my motor to get 280 horsepower. That is a gross waste of funds. Someone with a 305 tbi on NOS could smoke you.
But anyways good luck with whatever you decide to do.

BTW the stroker kit can't just be transplanted into a 350 block for a 383 for the same reason a 305 crank won't work in a 350.
Mallory metal is expensive and it will require alot of it.

I'll give you a nice sobering thought Cloud:
It will cost you less by far to get a 350 block and simply rebuild it, than to build that other thing. The only justification I can see for that combo is to keep a numbers-matching car together. Other than that, you are simply using your own money as the weapon to slow yourself down with.
And no I'm not bashing the 305, it's a perfectly good motor as far as it goes. But the fact of the matter is that every $$$ you spend on it doesn't go as far as the same $$$ spent on a 350.
Or, to put it another way: if you already have to get another block, it will cost you the same almost to the penny to build a 383 as it will to build a 335.
Hmmmm..... now that's a real tough choice for you..... yes mr. machine shop, I'll take one of those 335s to go, and set me up with the 50 free cubic inches...... but first let me step outside and consult my financial adviser right quick and see if that makes sense....

What is it with people is what I want to know.. why is it that people build up this opinion, and feel they need to slam other people.
My roomate had a 2000 mustang and a few people here and there (these type of people Im describing) all they did is insist on saying to him.. why did you get the v6 one, thats a piece of junk, why would you waste your money on that slow *** v6, and all this stuff. he just traded it in for a Hyundai Tiberon.. Now personally I really would't have bought either car, but I never dissed his car, or slammed it. It's a brand new car, and he likes it.. thats all that matters.. this guy wants to beef up his 305, and he is content with that.. just because someone else feels differently, and beefing up a 305 isn't enough to satisfy their need to have to try to be better than everyone else, and always have something better than other people do. why can't people chill.. hes content with his decision and would just like simple answers to the questions he is asking about the project he has in mind.
I'm not trying to start a rumble here.. I think this is total truth and maybe.. or I should say hopefully when read by everyone.. I hope that even the "bad guys" so to speak which aren't necesarrily bad people, they just go about things wrong, will say hey.. ya know this guys right!! maybe I need to stop criticizing so much, and just try to be helpful about answering the questions at hand, or atleast voice the opinion in a diginified way instead of saying, "why polish a turd" or "inferior motor" the 305 is not an inferior motor. it's actually a strong running good motor. and it can be with the right things done to it, beefed up to a point that might just make those certain people that can be "content" with the outcome of that project, and those people don't feel that same feeling that you would feel like they got cheated, or that they wished they would have gone with a bigger better, and badder, and more powerful.. etc.. etc.. because they are happy with theirs.. thats why there is 4 cyl cars, and v6 cars, and v8's and v16's.. there is variety cuz some people are happy with less, and some people want more.. the ones that want more... should not criticize the ones that are happy with less.. respect them, and their opinions.. their differences makes the world more interesting.. it would suck if everyone in the world.. all liked the same exact things.. nothing would be cool about owning a souped up 350 if everyone had one.. cuz you wouldn't have the content little 4 cylinder rice car drivers to pass by roaring your loud flowmasters pass their tinny coffee can cars. hehehehe..

Thank you very much Bluebird He does have a point I am going to be Content with what I'm spending and Why would'nt you guys support anyone else on this board with there opinion or ideas we're all 3rd gen owners jeez ya'd think we'd all have a respect for each other.....Anyhow The shop that I've gone to it's in Albany N.Y and there called Mccabes Auto and they will tell you.....It's not worth it to put in a 350 engine in this car your better off getting the original 305 that came with the car now if there's anything you'd like different I could tell him and he'd do it for a reasonable price.......While flipping through an old Super Chevy Mag I found an article on the Silver Streak car.....Now I might not have liked the way the Silver Streak looked but oh well......What I did like was the motor...I'm looking for an engine in which I won't have to spend huge amounts of money to make it go.....I called up the shop again and because I've had a lot of work done on the old engine they said ok "we'll bring down the price a lil because I know how much money money you've been putting into your old engine" (Gaskets, Oil leaks,etc....) He said "I'll do the original 305 TPI for $1800 give or take $200 that's 170 horse"......That's when I said ya know the 170 horse don't really cut it all that much for me is there anything you could do to maybe boost it up?" He says" Well I could put a 350 in for about $3750 because I'd have to reprogram your computer and that would run you up in price everything would have to match your car that is originally a 305...." So I said well I found this 305 engine build up kit that puts out around 270 horse.....So I gave him the # for powerhouse told him to call me back when he's done....He called me back and said alright It'll be about $2600 give or take $200 if they run into problems.....That's almost $1100 less then what they wanna charge me for a 350 block without any rebuild....for maybe a lil less the power......With that $1100 I'd be able to save it and buy an Tranny next year without a problem instead of paying through my nose to put in a 350 and paying for a tranny next year that's almoist $5000 when I could only spend 3750-4000 total for both....

In the long run I think it would be benificial...I'm not looking to goto the track.... or race numerous people on the streets that's not what the goal of it is I'm just a lil discontent with what the original 305 can put out I would like a 305 to put out as much if not more than some 350's on the road...remember an 87 Z-28 only put out 170 horse and an 87 Z-28 350 only put out like 210-220 horse......If an 305 puts out at least 270 horse while at an affordable cost, then I'd like it...I'm not lookin to get 10 sec time slips or 0-60 in 4 seconds...That is'nt my goal I would like this as a project car and a fun weekend summer car to just cruise out in the open air...I mean is'nt that why car enthusiasts get motivated to do what they do.....I'm also not looking to beat the hell out of a 350 engine and sell it to some poor highschool kid because I'd rather make my car as nice as it can be without straying to far....I'm only 18 and I've known that and 87 Iroc-z Has been the car I've loved and always wanted now that I have one I love it more and more everyday even though I'm putting in a 335 or doing something a little different means that I love my car and I am an enthusiast just like many people on this board.....I bet there's many people that never drive there 87 IROC or 91 Formula....They just love there cars and only drive them for the pure aspiration of driving a car that they know they've restored or know there's not one bit of rust on the floorpans or panels....These people are enthusiasts like me who do all the can to preserve something that will be forever there's.......And that's all I have to say about that.....

Now to get back to business.......I think almost 100 horse over the existing 305 is great that's what it should be....Anyhow It should be around $2600 with all new accesories cept my new alternator.....What sux is that I have the TPI so there like damn why can't he just have the carb it's so much easier don't have to deal with vacuum lines....

CloudIROC: If you need a 305 roller cam block, shoot me a note or whatever get on the thruway south and come pick it up at my house. It's was sitting outside all winter but it was in decent shape and considering you'll take it to the machine shop and have it bored out and cleaned up anyway what's the difference. It came out of the Chicken - had 96K mile when I removed it. Otherwise it's going to the junk heap.
If you want a decent '87 350 2 bolt main marine block I have one of those also but I have to get $75 for that - that's what it cost me. I picked myself up a 4 bolt main block at Rhinebeck last week.

ooo that might be nice..... But I think I wanna go with a new block um oops sorry I did'nt know what came in the stroker kit....Does anyone know what would have to be done to the block itself....I don't think it has to be bored...I think the crank is what gives it the more power?

Any block new or old will have to be "clearanced" as the stroke is longer. Clearancing usually takes place on the oil pan rails, and at the bottom of the cylinders, but if your having it assembled by someone else (is that right?) they will do all the work required. If the block is not clearanced the engine will not rotate.
Um thanx I am having it done by someone else So they'd do it.....I'm gonna call up today and ask how much it's gonna be......

Don't listen to the people who say the 305 is a turd. It's incredible the amount of ignorance displayed by them. Check out the following articles:

Those are awesome numbers man. The key to producing high high power is an appropriate cam and heads match. The 350 has a mere 15% more inches than the 305, the exact SAME physical phenomenon applies to 305s and 350s!!!!!

Does anyone know what would have to be done to the block itself....I don't think it has to be bored...I think the crank is what gives it the more power?

The ONLY way this makes any sense is if you don't have to pay for a block. Obviously (from my sig), I'm building a 305; I had the information in my original reply because I had already researched the 335.
If you can pick up a 305 block free, go ahead and do this. BUT, if you look carefully, 383 rotating kits are actually LESS than the 335 rotating kits! So, you may actually spend less money building a 383 than you would a 335 if you can get a 350 block cheap enough since the machining cost will be the same. As for whether it is worth it to put a 350 (or something bigger) in your car: If it isn't, then it isn't worth it to put in a 335!
Obviously, again, a charge of "305-bashing" against me isn't going to stick. So, consider your course carefully. We're not bashing, we're offering advice.

Well Actuality I'm gonna have the guy at this shop where I'm gonna have the engine installed Give me a price of the original 305 the 335 price and a 350 price if the 350 price is'nt far off from the 335 then I'm gonna go for the 350 but if the 350 price is way out there then I'm gonna say 335....what sux is that I don't have much experience in the engine department so Iwoul'dnt be able to do it myself...

DO THE 350!!! I don't know if you realize this but a 350 has the same size and shape of block that the 305 does.. Just a different bore/stroke ratio.
350 or 335 either way you will have to reprogram your computer to get the full advantage of it.

Brian I'm not knocking on the 350.... But I'm thinking I'm not gonna have Transportation for a while if the 350 is too much.....Hopefully when they get the engine in either the 335 or the 350 my tranny won't bust or any of my rear end members won't go my car does have 115,000 on it and all stock so hopefully nothing will go....I'm thinking if I do go 350 then it'll increase the chances of something going....But If I do get a 350 It's gonna be a stock ac delco anyone know how much these put out????

My advice is to beef up your tranny and rear before you swap in a more powerful motor...
Or else you'll have a 87 camaro with a new motor collecting dust in your driveway while you save up for a new tranny.

This year I'm not getting the motor next year I am I am either going to get a paint job after the motor is in or I'm getting the tranny with the engine.....Decisions, ecisions!!! hummmmm I think I'm gonna get a new paint job first,,,then in the winter off next year get a new tranny....then when the spring rolls by I'll get the new rear end......And I'll be all set mechanical wise I won't be driving it in the fall/winter so I'll be towing it many places....

If you're lucky you'll be able to run with stock LT1s.. Meanwhile I'll drop in a 355 that I found for $700 that will put my car into low 13s.[/B][/QUOTE]
stock ls-1's are running 13.10;s now in the vette, and some people want an odd combo, get away from the trendy vibe

First there is a guy believe name is Preston Smith running nines in an Iroc that has a supercharged 305(true he did kill the original block and had to go to an SB2 but it still is 305). Secondly i am getting ready to swap a 305TPI in place of a 305 HO. I would love to do a 350 but money forbids and i have the donor car with a 305 so thats what i am going to do. Stroking a motor is not cheap. like they said you usually have to machine the block and that is not an easy or cheap task. If you could find a low mileage 350 TPI it would be a basic swap. You did not say what you have done to your 305 now but if you did some basic bolt ons it would be a strong runner. Also everyone is getting hung up on horse. Horse is great for drag racing a 1/4 mile at a time but if you want to have a car that puts you in the seat and has nice driving characteristics then you want torque. Where torque is concerned there is no replacement for displacement. As far as the reprogramming from everything i have ever heard the stock 305 computer is the same if you got a 350 TPI you would just need a 350 prom chip . The 335 is going to need a customed burnt chip to match the fuel curve and unless the people building the engine have built one before and knows what it needs this might not be a one shot deal. I would just look at all options and shop around before i went into stroker. My friend has a 383 and he has had problems with it. He tried to run it with his computer and had a custom chip burnt 3 times never could get car to run right. Had to ditch computer and now runs it without. Antoher uy we knows put a little money into his 350 still has factory computer and runs like a beast. These are both Monte Carlos not f bodies but the point is the stroker is more finicky. Either way as long as your happy with it that's all that matters. Its your car not anyone elses so it all depends on what you like. Have fun and good luck.
Well I've made up my mind thank you everybody for opening my mind to what is what in the thirdgen world so I'll be getting a new 305 block with new heads and everything maybe instead of wasting half my money I'll just get a full blown exhaust....Thanx guys a 305 TPI is fine for me.....I have to get a new Tranny and paint job sometime anyhow so I'll have money for those when they come....
