does anyone know of a good place to grab a stroker crank that will fit into a 305 and to make 335ci? I want a lighter crank than stock. So since im gonna tear down the motor and build it back up does anyone know about a good set of 305 pistons, rods, and a good crank. Maybe a cam to work with Vortec heads. Any input will be helpful except telling me to do the 350 deal. I dont have the cash for a 350 block. But it would be nice if i can find one for cheap. Money is a BIG issue im in high school on a very limited budget. If anyone knows where I can find a good 350 for cheap that would be great as well.

I thought a 305 stroked was a 334? could be wrong though. I hear it's a pain and not worth it to stroke a 305. I'd say stroke a 350.

Morley

Yeah the 334 stroker is a neat idea but the most they were able to get out of it was 329HP.
If you just like the idea of a stroker go with the 383. If you just want a replacement engine, go with a new 350 and when it comes time to rebuild it have it bored and stroked then.

streetrunner

thanks. Now where can i find a really good priced 350 i would rather have a new casting complete for a small price but i will take what i can get. I that when u wanna play you gotta pay. But i am on a reely limited budget.

Did anyone ever see Chevys 302 Camaro. I think it was 2001 or something like that to commemorate a 69 Z28 302. the destroked the 350 to a 302 and it revved to about 7500 I think but it putout mad numbers. It was silver. I read it in my motor Trend I think. It pumpedout like 375 horse though or something like that. I know it was a bunch. I'll try to find more on it I dont think it went into production though.

Stroking a 305 is is costly, I built one last summer, Just used a 400 crank had it turned down and internally (sp) balanced, so I could use the 305 balancer and flex plate, I used a set of 5.56 rods resized with ARP waveloc rod bolts, I put a crane fireball II cam with 302 adv. duration and .480 lift and It had a set of heads of a 92 chevy truck on it.I was impressed with how hard it ran for no more motor than I had. There is a place in bakersfield Ca. called Powerhouse that sells rotating assemblies to build a 10:1 335. The number is 805-861-0167. If I remember right it was around 500 for everything minus the crank.

streetrunner

32789RS, how well does your 327 perform? How much did it cost and where did u get one from? I was just looking into that motor. Do you have any knowledge of what I would ahve to do to keep my stock TBI or switch to a TPI? I wouldnt thik anything since it is basically a 350 but destroked. I kinda wanna get something that is a little different than what the other guy has. you know? What are the power number for it as well? I have a 5-speed and it cant handle too much torque thats why i dont wanna go to a stroked 350 or a 350 at all. I think my tranny can only handle upwards of 300-325 lb ft.

streetrunner

with that kind of compression ratio do you have to run race gas? or 93 with octane booster? Have you ever had any problems with detonation? That looks like a KILLER combo for a third gen. What are you running in the quarter? Im guessing low 12's high 11's

32789RS

The motor performs real well, IMO the heads are why this motor runs as hard as it does. I bought the short block from a friend for $250 and all I did was polish the crank, put new bearings, rings, cam, lifters, oil pump, timing chain, and a new set of heads on it. I dont do much with fuel injection, so i'm not sure what would have to be dont to keep the tbi, I don't have the power #'s just yet.

Ed Maher

If you can't afford a 350, you can't afford to stroke a 305.

Marshall89ws6

you can afford it...... the 350 would b much more costly b/c of all the computer changes and such.... and even if you didnt have a comp youd have to get an all new intake manifold and carb and all that expensive junk..... stroke the 305.... it is supposed to add about 100 ponys...... but i hear u have to change the oil a whole lot. its worth it i think...... i think getting a car to 300 or 300+ hp is enough for someone in high skool

Ed Maher

You would have to do the same computer changes to go to a 334.

I'm just trying to help you here. You can get a perfectly rebuildable, or even running 350 for MUCH LESS money than you'll spend on the parts for the 334. And the 334 requires special machining to clearance for the longer stroke as well as special externally balanced flywheel and harmonic balancer. All of that costs money. And it would still be slower than the 350.

If you're still in high school, and you also believe claims like just adding a stroker crank will give you 100hp then I'm pretty sure you should be trying to learn as much as possible, not just blindly bash the people who have been around the block.

32789RS

I run 110 octane leaded racing fuel, I have given thought to trying to 93 with octane booster, but hasn't went past a thought. I'm still working out the bugs so I havn't been to the track, I'm hoping to take it next weekend if I get my new converter this weekend. I'm hoping it will run mid 12's on the motor and high 11's on the bottle. I'll post the results when I finally make it to the strip.

ME Leigh

Building a stroked 305 is really cool, but why would you do this if you could get a 350 with better heads, and still wipe ***? A stroked would be cool to say you just got smacked by a stroked 305. But it is cheaper to just get a 350 block and re-ring it for 50,000 miles and then build a 383.

32789RS

When i first built this motor it was for a circle track race car the rules said max. cubes for a chevy were a 305, but I noticed that they never tore the engines down so I figured I'd get away with it.

Streetrunner, I have to go with Ed on this one. Powerhouse sells the 334 rotating kit for $599, plus $200 for the externally balanced damper and flexplate. Guess what? Their price for a 383 kit is the same!

Okay, what are we looking at here? $850 (remember shipping) for the rotating assembly, plus the boring required, plus the pan rail clearancing, you're well over $1000. For 334 cubic inches.

If you can't find a 350 core and rebuild it for $1000 (which will be 355 cubes if .030" over), then you aren't trying hard enough.

You don't say what induction you plan on using, but the computer should be happy with either engine if you use a computer-compatible cam.

Either way, without exhaust upgrades, neither engine is going to be happy, anyway.

Some other points: The 334 is going to be choked with unmodified 305 heads. Either port the stock heads (unless they're TBI heads - dump them if that's the case), or go aftermarket. The same is almost always true for factory 350 heads - either work them over, or go aftermarket. I know you are budget-limited, but those are the facts of life.

motorhedfred

The problem with the 305 is, and always will be the 3.75 bore. It doesn't allow a large enough valve for good breathing. You could probably stroke a 305 to somewhere around 355, but it would require special pistons which no one makes.
You have to realize that the 305 has the same stroke as a 350, but a smaller bore that can't be opened up to the 4" 350 size. I'm told by the guys at Trick Flow that a Gen 1 Twisted Wedge head is the only one that you can get 2.02" intake valves to fit on a 305 block with, and that's only with at least a .030" overbore.
Stroking the 305 is possible with Keith Black hyperutectic pistons but you'll only compound the breathing problem and with the Gen 1 Twisted Wedge heads (no longer available new) you can only go .500" lift at the valve without cutting different valve notches in the piston tops. This is because these Trick Flow heads used a different valve angle.
Nothing's ever as easy as it may first seem is it....: (

Chevy's reply to Fords new Gt-40 is a Camaro 8.4L 525 ci. Aluminum block and pushrod 8 cylinder w/ 770 stock hp and 680 ft lbs. Run low 10's in the quarter w/ a top end speed of around 230 mph

i always thought the only difference between the 87 up 305 and 350 block was the bore? i know the 350 and 305 crank are the same stroke so why couldn't you put in a 383 1 peice seal crank form scat, and remove enough material to balance it with the lighter 305 peices? think about it what hp do new ls1's have 330? so a good 305 stroker with say some afr competition 180's and a good cam... can anyone say 400hp? that would be the ultimate 305!! personally i like the nastalgic 302, cmon chevy had like 390 horses when it was in the camaro, ford just couldn't get it right... also i remeber seeing the new camaro in a mag with the 302... it was a custom job some dude had built..

later badgta

Morley

Except that the only large valved heads that fit the 334 stroker were the first gen trickflows and they only got 329 hp tops with that combo. Without good heads it is a dead subject.

To be different requires cash. If you are truely on a very limited budget as you say about the only thing that you can afford to stroke is yourself.

1.Do mod's to the 305 that you can later install on a larger engine when the time comes if you still want one.

2. The exhaust needs to be replaced from the heads to the tailpipe.

3. Install a better breather of your choice. The stock breather is as bad as the stock exhaust.

4. Get a rear end assy from a V6 car for cheap and install the complete assy. No special skills or tools required.

Even these things will take some cash. But they are basic and will work without any computor prom changes and you will be able to tell the diff. Just don't expect it to run like a Nascar engine.

streetrunner

hey DM91RS how wel does your combonation of parts work and how much cash did it take?
I am planning on using the stock TBI comp with my modified TB Bored to 48 mm and fuel press reg. Allthough i hav a friend with a 87 IROC who may go with a carb and give me his TPI setup.
The exhaust modifications are on next summer's agenda. I think I may just let the 305 die and go with either the 327 or 350. Im starting to see that not many of the parts for 305 can be easily swapped onto a 350 so (money pit). So I'm doing some calculating to see what would be cheaper. The 305 buildup then go to a 350 later or juss let 305 die and go with 327 or 350 later. Thanks for all your input. Im getting to learn alot.

streetrunner

i just want to smoke the hell outa this 5.0 mustang and 97 1.8L VTEC Integra. Their **** talking is pissing me off.

DM91RS

streetrunner....

My combo runs well.

The top three to me are breather, exhaust and rear gears. And like I said they are all reusable.

Hope this helps

dbarker02

is it just me or isnt the block from the 305 the same as the one from the 350.. just put on the 350 heads & guts... & your done... right? i might be mistaken... ??

ME Leigh

No the 305 and the 350 are not the same block they have different bore sizes, but they are still both small-blocks, with the same exterior dimensions and shape.

streetrunner

ok all your input is helping shop and decide what im going to do. Another option that i am not ruling out is going to either 3.73's or 3.42's. What kind of gas mileage do yall get with those gears with a T-5. is it a big difference? It would be the quickest way to wax the hell outa the gs-r but i dunno about that mustang GT. I think. I want your opinions on this.

streetrunner

The top three to me are breather, exhaust and rear gears. And like I said they are all reusable. So if I can grab all of this what kind of improvements will I see? With some rear gears. I think that If I can get my family involved with sending me money for b-day that I can come up with enough cash to go ahead and do it all. headers, catback would be the exhaust. vortec heads and 1.6 rockers with stock cam and moded TB would be the lungs. Then 3.73's or 3.42's would be bthe rear. what kind of improvemnts would i see. and how much oif a decrease in gas mileage would i see do u think?

five7kid

iTrader: (14)

That's typically what you go for. Results vary.
Ugh. Don't like that combo at all. Vortec heads = new, unique, expensive base. Stock cam = lame. Instead, port your heads, pleunum & base; spend your money on things like a real aftermarket cam, runners, TB, & adjustable fuel pressure regulator.

With those things and exhaust & gears, the improvement will be vast. Should at least put a scare into if not put away those Stangs. Done on a 350 - no problem (of course, your T5 may have a different opinion).

streetrunner

five7kid i have a TBI no TPI. Porting those heads are no good.
im sorry if i did not make that clear earlier. i have a L03. no LG4 or L98 or LB9
but 1.6 rockers would pick up the lift and give some what of a noticable increase in power right? With the vortecs i have to go with self aligning rockers which means i need new rockers. correct? so why not go with 1.6 when 1.5's are about the same price. and the cam for my car has to a hydrolic roller so thats 250. then i dont have to go with all that radical of a cam later. am i correct when i say any of this? this is all **** i ahve read or heard so if its wrong oh well.

Confuzed1

iTrader: (4)

I know I get horrbile milage with my gears!!!! If you decide to get 3.73:1 gears,.....be prepared.

But the launch you'll get off the line is awesome!

If I get 11 MPG.....I'm lucky.

five7kid

iTrader: (14)

Runner, I didn't pick up on the LO3 part. You're right about the vanity of porting them, but the same applies to the 1.6 rockers on them. You should be able to pick up a set of LB9 heads for very little coin and work on them.

Better breathing, either those heads or Vortecs, isn't going to do much without a cam change. Factory cams are just plain lame.

streetrunner

yea i have been doing alot of research on my particular motor and others that have used different heads and what kind of results they got from them. I know my T-5 isnt up to the challege of much over 300 lb ft. but when that goes away im grabbing me a T 56. My stock cam has a very short duration and very mild lift. Not intended at al to be a hot rod cam. I think all i will do is juss put the 3 73 in there and see what jappens allthough, now i get about 18 to 20 in the city and 24 on the highwaycruising at 60. soi dunno whats gunna happen with all of that. Would 3 42's give me a reel good launch and acceleration that i would need to wax the hell outa my boys integra? (VTEC 5 Speed all that bul ****). The gas mileage is the only thing that woories me and if i had that T-56 none of this would be a problem. Anyone any good palces to salvage a wrecked 28's 6 speed? maybe with the LT-1 or LS-1 munted o it?

streetrunner

yea i ahd a friend who had wrecked his 87 iroc it had LB9 the 305 TPI. he was gunna give me the whole damn TPI i could have stripped more off of it if i had wanted but he sold the whole car for 300$. the damn TPI was worth 300. it pissed me off.

what would a posi do for me with 3 73 or 3 42's? im specificaly looking at the auburn gear pro series posi for my 8.5" 10 bolt.
