I was just wondering what everyone here thinks about stroking the 305 to a 335. You dont have to dog it or anything, just give me your opinions.

And yes, i know a 350+ is better...

 

Go for it. It is something different. It should make fairly decent power. Not 355 or 383 power, but good power.

 

i wouldnt do it... ONLY because for the same price of doing a 335 i could go 355 but if thats what you want to do im not puttin ya down or anything just want to tell you its gonna cost approximately the same for a 355 and you will get more power for the buck... IDK if you car but w/e just lettin ya know

It is okay but I wouldn't do it. You can make decent power out of one but it won't be an RPM monster by any means. The power gains do not justify the cost.

 

You could build a 383 for almost the same price maybe even less actually, depending on the price of overbore pistons for a 305 compared to pistons for a 350.

The only reason for doing a 335 stroker is if you really need to do something different or if you have money to burn.

 

Yup I agree.

 

If you decide to go with the 335, Powerhouse out of Bakersfield, CA has a 1 piece 335 kit for a little over $800.00. I was planning that route but went with a 350 bored 0.040.

 

$800, that would get you started on forged goodies(heck maybe the complete bottom end) for a 350 - that is if you already have one. I considered 335 but thats not cost effective- when you put the Power gains from a 335 next to the gains of a 350, you can see where it stands and the best place to put your $

 

A 335 would be a cool toy only if people could realize noone wants to pay $800 for the kit. I shurely would build one for say 600 for the internals but i wolnt pay 800 then you gota go get your block machined ect. so in the idea for power to $ ratio its sucide lol. but think like this if its what you liek and you want it go for it i mean look at that "Flyinlow92" guy he spent 10k on a ls1 t-56 swap. shure it wasnt a good idea to pay i think 8k for an ls1 with t-56 nitrous system and exaust and 2000 for someone else to put it in but he did and aslong as hes happy it doesnt matter what the others think. so if your on a budget its a bad idea but if you have money out the **** then a 335 TBI would be a cool little motor .

 

I think 10k is well spent to possibly run high 11's on the juice and low 12's off of it all while knocking down 29mpg.

 

Yup, technology is our friend...

oh and on the 335 idea, i dont like it

 

My dad and i looked at the powerhouse kit, but he didnt like it cause if you read the very, very fine print i believe it said something about used parts. i could be mistaken, but im pretty sure thats what i said.

I know it would be more cost effective and wise to build a 350, yeck, i have a free set of super lightweight rods and pistions worth well over $1200 for a 350!!!!! But thats beside the point, i was just curious cause its still out there on the table.

Also, what ECM and knock sensor would i have to use if i decided to pop in a 335?

 

It's a 305 block so use the 305 esc and sensor.

Steve

 

i think 10k is a waste you can build a nice tpi or tbi set up for half the price and puls by donig the engine work yourself you learn marketable skills. jsut my opinion

 

But then you cant say, "Yeah, I got an LS1 in 'er"

Its allllll about the bragging rights

 

I think the idea of a 335 is pretty cool. I knew someone that did it and it was a torque monster...beat the hell out of any decently modded (all the bolt ons, etc.) 350 on the street, no lie. But if you think about it...do a 335, some vortec heads to keep compression down, then throw a turbo or superchager on it and you'd have a stout little engine that could run with just about anything out there...Willie did it with only a 305, so adding 30ci could be that much more of a benefit. However, everyone on here is right, dollar for power, 350 can't be beat.

 

The problem is that there is no such thing as just throwing boosted induction on a TBI set-up. Can it be done? yes. Is it a weekend project? absolutely not.

 

did i hear boosted tbi?

 

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^Sweet

 

This 335 idea has been out there for a long time now. I want someone, anyone, to post some times or HP to this enigine. Every few months someone starts this thread, and of course everyone agrees its not money well spent. But its to the point where i want to see some actual numbers for a 335 just because the topic comes up so often. and no one has done it.

 

I only know of one person that has done it and it is with TPI. I believe he makes 333 at the crank.

 

I was one of the ones that opened up a thread wanting to do it. I then realized the cost-effectiveness of it and decided to go with a 406 instead. I think the reason no one has done it is eventually they realize that it just isn't worth it. I'm sure the guy that has done it has decent horsepower and impressive torque numbers, but for the vast majority of people it just turns out to not be worth the money and the trouble.

By the way nice sig Teal :hail:

 

Some lesser known confucian sayings:

Man who chooses 406 is wise.

He who brags with taillights need not brag.



He who builds 335 not very smart.

 

You guys keep saying get a 350 instead of a stroker 305 because its money well spent but if you allready have a 305 and you do not have a 350 in the garage why is it cheaper. I would think its cheaper to stroke it then replace it. I could be wrong I have never priced it. I have always considered it as a possibliity. What would it cost to buy a crate 350 and have it installed compared to taking your 305 and kicking it up a notch to 335???

 

Whoa, this was brought back from the dead.

But you may be right, Sgt. If you dont have a 350 laying around but have a 305, it COULD be cheaper. Just depends on what else you have laying around.

 

From what I have seen, a decent set of pistons is hard to find and rather costly due to the odd bore size, whereas 350 components can be had for a dime a dozen. So on a 305 the pistons would be the biggest issue in rebuidling.

Here's a link to a 305 to 340 kit:
http://speedomotive.com/sbc_305_to_3...oker_crank.htm

not to bad actually since even with 64cc heads you'd have decent compression. Still though, a seasoned 350 block isn't all that hard to find and the little extra junkyard searching will pay off a lot more in the long run as opposed to building a 335 stroker. the novelty of the idea is still pretty cool though.

 

i think the kit costs like 700 on engine kits and if you have tb you get like 95hp and if you have carb you get even less. so you'll have like 256hp. i think it would be pretty cool to have something different like that, but like the people are saying, i just built a 358 with everthing new for alittle under 1100

 

I agree. This is the problem I ran into. I have a 305 and it would be more expensive to go for a 350 then to keep my 305 and stroke it. I am also getting a good deal on labor though so thats something to consider. If you've priced new 350 longblocks and consider core charges then u will see its really not cheaper to get a 350.

 

By the time you buy the kit and have it professionally installed you will end up paying more than a 350 shortblock. You would only save money if you could do all the work yourself with no added cost for any machine work. You can get a new roller 350 base for less than 1500 (with no core) and a used low mileage vortec shortblock for just a fraction of that. The 335 is a cool idea but you are going to spend way more than 1500 bucks when it is all said and done.

 

i just priced the kit and it is not 800 it is 500 something then you have to balance your own flywheel if you have a 5 spd because they will balance the kit with the flex plate. also the guy said realistically you will only get about 65 hp from this set up so thats alot of mulah for 65 hp... go buy the cheap nos kit for a truck and you'll get more power than that at a cheaper price.
also your block will have to be machined in certain spots so the 400 crank won't hit anything so by the time you get done it may very well be 800 bucks but the kit is 5 something plus you will have to add up all the time it takes to build the thing.
i have seen used 350 for 100 bucks in the shopper papers you could buld one of these the 383 stroker kit from powerhouse is like 480 bucks its cheaper and you will get mo power from it.
but i think it would still be cool to have a 335 cause it is a rare thing but if you are looking for cost effective go with a 350.
but its cool to be unique if you want to spend the money and put forth the effort.

 

I know this is an old thread but there is somthing about it that is nagging me. I also was looking into building the LG-4 in my T/A into a 335. But my buddy was getting rid of a 350 and sold it to me for cheap. For me it was a no brainer, 355 = more power.

What is nagging me is, why do you have to buy a "kit" to get some "special" pistons? I have never built one of these engines so I don't know, but I am wondering why it seems that everyone is talking about high cost of special pistons.

Like I said, I have never built one of these engines so I could be very wrong, but, isnt a 335 just a 305 with a turned down 400 crank, 400 rods and 305 pistons. I know that back in the 80's when I was in highschool, when you bought a 383 from P.A.W., it was just a 30 over 350 with 350 pistons and 400 rods and crank. The shorter rods (5.565 inch) compensated for the longer stroke (3.75) and allowed for the use of the stock (or +0.030, 0.040 etc.) 350 pistons. Won't this work with the 305 also since it shares the same stroke as the 350? Or is their an issue with the 305's block that won't allow the use of the shorter rod?

 

The big thing is that if your 305 needs any machine work at all, then you may as well get a 350. The cost of a core bare block is usually 100 dollars or less. The machine work costs the same, you'll need different pistons, but the other stuff will all work. And BTW, dont think that a balenced kit from powerhouse will truly be balenced, have it done again, and you will see what I mean.

 

335 pistons are not cheap because no one makes any kind of hi-perf 305 pistons for anything nearly as cheap as hi-pef 350 pistons (if you use 400 short rods) and almost no one makes 335 pistons (for 5.7" rods), and certainly not for a reasonable price, like 383 pistons.

Also, I'm not entirely sure about this one, but there may be more clearance grinding involved on a 305 block over whats needed on a 350 block. Don't take my word for it on that one though.

 

400 rods are shorter, and allow the use of 305 pistons in a 334 or 350 pistons in a 383. However, it makes an already less than optimum rod/stroke ratio even less so. Therefore, "special" pistons for a 3.75" stroke and 3.766" bore with 5.7" rods.

Is there anything else that needs to be unlearned about this combination?

 

The question gets posted every couple wks, in most cases guys get talked out of it.
In fact, I don't see anyone chiming in that says they've gone ahead and done it.
I might try it sometime, but if I do it will be for my truck.

You don't have to buy a kit, KB sells a piston that works with the 3.736" bore, 3.75" stroke and a 5.7 rod.

What do you mean by unlearned?

 

As Streetiron85 said, this comes up every few weeks on one forum or another when someone "learns" about this "neat new 305 stroker kit". They come on here to "teach" us about this new technology, and then we spend 35 responses "unlearning" them about the great power gains to be had just by installing it. Personally, I had to be "unlearned" in April, 2001, when at a swap meet and talking to the engine builder that did my 396 shortblock. I already had a roller 305 block and ZZ4 cam, why not stroke it with the Powerhouse kit, I thought. He told me he'd sell me a builder roller 350 block for less than the difference between the cost of a 334 rotating assembly and a 383 rotating assembly. The machining costs were the same whether 334 or 383.

Now, if you can build a 383 for the same or less money than building a 334, even if you already have a 305 block but not a 350 block, why would you even consider a 334?

Why buy a kit? Because it will probably cost you less than pistons, rings, crank, bearings, and gaskets purchased separately.

And, I haven't seen this $500 kit, either at the posted Speedomotive link (over $700 for the "basic" kit) or Powerhouse. With the latter, it's $599 for the rotating assy, and $199 for externally weighted damper & flexplate. That's close enough to $800 in my book. A "basic" Powerhouse 383 kit is $489.

And, for the record, I keep calling it "334" instead of "335" because a .030"-over 3.736" bore with a 3.75" stroke and 8 cylinders equals 334.173 cubic inches. Doesn't even round off (up) to 335.

 

I get it, understood and agreed with.

 

I keep on hoping that someone will build one.
That way every time the question gets posted, there'd be at least one guy here who could say "yeah I tried it".
When / if I retire, I'll build one, if nobody else has.

 

Somebody here did in fact build one; it's a LB9.

Makes EXACTLY the same HP as my carbed 305 (stock stroke) does, within a tenth of a HP IIRC; and proportinately more torque than my 305, within a couple of percent of being in direct proportion to the cubic inch difference.

In other words, it does exactly what one would expect; no more, and no less.

Problem is, it cost the guy about $500 more than it would have to put a 350 short block in there instead, and didn't do as much.

It's always funny as hell to see people tell us all about that "95 HP improvement!!!!" in the ad. It takes a real sucker to fall for that one. Like, you're going to take a motor, let's say a LB9 with 200 HP; that's 2/3 HP per cu in, right? And you're going to add roughly 30 cu in to it, right? And each of those additional 30 cu in is somehow going to produce 3 HP per cu in, which is somewhat more than 4 times as much power than the cubic inches that are already in there now are producing???? On what planet? Is that before or after you stick one of those Tornado things in your intake and put a cow magnet on your fuel line and the $15 IAT replacement with $12.50 S&H off of ebay that gets you a $.05 resistor in the mail? IMHO, quoting that ad seriously as if it's the truth, instantly qualifies someone as gullible, ignorant, and is generally the sort of person who will believe anything anybody tells him if it's what he wants to hear.... in a word, a sucker. Easily distracted by shiny things and then parted from his money.

 

This one made me laugh! That's funny.
