Has anyone converted their 305 to a 335 stroker with the kit from Powerhouse. What kind of results did you get?

 

Dont polish a turd. Put in a 350 engine, or larger. Search this board for the reasons why.

 

Dude that was lame! He has a 305 and for reasons i'm sure is going to keep it.My uncle just did the stroker kit and i was impressed, i am going to do it also when spring comes.Always telling everyone to yank out the 305 is bull****! Cheap mods will do wonders and creep up on a 350.My 305 is staying

 

Why does everyone bash the 305? My 305 can beat any 350 around here even the old ones(you know the ones with horsepower). I beat my friends chevelle with his 350 by about 30 car lengths so I say go with the 305 stroker kit and make all those 350 boys jelous. You can mod out a 305 to be just as fast or faster than any 350 if you do it right so go for it. Now where is this stroker kit cause i want one too.

 

Which "old" 305's had "horsepower" ? I think the highest rated 305's where the 1996-1999 Vortec engines, but I could be mistaken. I here what you guys are saying about your 305's. Mod what you have. It's your money, do what you want with it.

 

He said old 350's, not 305's...And there are some of us who would prefer to keep our cars numbers matching...

 

LOL dont polish a turd.... that is great.... and Keven91Z knows stuff to.....
Heres the reason the 305 is a turd.... any GOOD engine has a bore of 4" or more.... sbc - 302, 327, 350, 383, 400 sbf 302 351 Guess when engines like the 305 and 307 have?????

 

Although I am building a 350 soon, I would have to defend the 305's. If you guys don't have anything better to say, just don't open the threads. I 've considered the stroker kit but decided against it since I got the 350 cheap. I think the stroker kit is cool if anyone wants to go through with it. And yes there are plenty of 305's that will stomp 350's. This is usually true since a lot of the guys who brag about their big 350s, don't take the time to tune them right to start with.

 

My bad I'm with you guys on building the 305's. It's what's in the car, go with it. Has anyone ever built a 335ci TPI engine?

 

Someone on this board had one. I just can't think of who it was.

 

Well if you think that 305's are such turds then how come my 305 can contend and beat 4th gen 350's with 310 hp? Its all about gears and building your engine right. And plus the 305's and 350'ths on third gen's came with about 10-20 hp difference. That is pretty bad for the 350's considering that they have 45 more fubic inches and only 10 more hp. Something is wrong there don't you think. Now I like 350's but I have a 305 so im gona stay with a 305. And now if you do your calculations also, 305's have more hp per cubic inch than the 350's almost every year thirdgens were alive. So you tell me whats wrong with that?

 

i guess that the fact that the torque rating from the 305 to the 350 jumping from around 280 to around 330 makes absolutly no sense whatsoever. its been beat to death millions of times, the stock tpi manifold isnt going to make a crapload of horsepower regardless if you put it on a 305, 350, 383, or 400. what will change significantly is the torque rating with each motor though

 

the biggest problem with 305's is the fact that the shrouding of the intake valve with the cylinder wall leads to poor airflow. Also this means that large valve heads won't fit either. Now would I stroke one? Sure, adding cubes will jazz one up nicely for a streeter adding both HP and torque, and this is fine for most people, not everyone wants or needs a fire breathing small block.

 

The shrouded valve issue will only be worse with a longer stroke. The closer you get to a 1:1 bore-stroke ratio, the more that airflow into and out of the chamber becomes an issue. This is why the 305 is inherently ineffective. Yes, the 305 can be made to produce stupid-high horsepower, but always at a cost greater than a larger cubic inch engine can do it. Stroking a 305 will cost a LOT more than building a 350. And what have you got? The satisfaction of knowing that although you kept a 305 block, you no longer have a 305, nor do you have a motor that is as fast as your money could have gotten you if you just built the damned 350. For those people that somehow feel they have something to prove by making a powerful 305, you're still defeating your own cause by stroking it. It's not a 305 anymore.

 

I guess you could call me a 305 guy, but man...it just doesnt make sense to build a 335. The cost of machining the 305 block to accept the larger crank will be more than buying a 350 block. 350 rebuild kits are cheap as hell, and everyone has a set of heads laying around that'll work well. The 305 is a great engine for what it does (make torque), I love mine. I have outrun a few 350's myself, but I know that with my exact same setup I will make more power and torque with a 350. If you want to make power you'll need what every powerful engine has had since the 60's...at least 4" bore. I'm not saying it cant be done, it just would cost more than building a 350 that will have more power and torque. period.

alright guys.. your all kinda off the mans question, he asked if anyone had any results from that conversion. If he wants to do a 335 and be different then let him. This board is not here to tell people what to do is it? i thought it was for insight. i know his setup should run 12's. you say how? a 335 with a NX nitrous kit is pretty potential if i say so myself. How many of you guys with 350s can say you run 12's? even if your not running nitrous. I am bias to a 350 but when he said he was going to do a 335 i thought it was a good idea. How many cars with 335's do you know of? not many, he wants to be different and suprise some 350's. If u want to argue about what is better a 350 or a 305 start a new post, or else help the guy out.

 

Take it from the man who tried to polish his turd first

In all seriousness, stroking a 305 really doesnt make much sense. About the only reasons I can think of to do it is if you need to keep a numbers matching block for show or emissions purposes. Or you just like to burn money. Performance wise, you will probably come close to a 350 since you are coming close to 350 cubes. For much less than the cost of that kit, I know I could find a running 350 and build that instead, and I wouldnt have to clearance the block so the crank would fit ok.

If you really want to do this, I would not buy a kit. I would scrounge up parts separately rather than buying what they want to sell you. The cheap kit is just that, cheap. Last thing you need to do when wringing out power is use cheap parts. Make a list of some decent stuff, or even call them and start substituting things like rings, bearings, pistons, and rods... and see where the price goes.

 

I don't remeber which magazine did it, but didn't the Silver Streak Camaro have a 335 in it? Assuming anyboyd knows what the hell I'm talking about

 

Yeah, I remember. Wasn't a bad combo with the T56.
They put a ton of money into it though.

 

I'd say go with the 335 Stroker, it's something different, hey if it works out maybe others like myself will do it. Good Luck and here's a link to superchevy's site, when they did the stroker kit from Powerhouse: http://www.superchevy-web.com/pastprojects.shtml

I will concur with Madmax as valid reasons to build a 335.

Install a Miniram, AFR 180s with 1.94/1.5 valves and a decent cam and yes, you can make that stroker 335 quite powerful - probably in the 350+ HP range (depending on cam choice).

But, if you did the same mods to a 350 (and you wouldn't have to stroke it either and you could go with even bigger valve/port AFRs) and you'll make even MORE power (with more TQ for the street) at a lower price EVEN when you add the cost of picking up a 350 core.

There is no V8 cheaper to rebuild that a SBC 350 - due to the shear volume. And if you REALLY want to make a stroker, then make a 383.

But if your reasons for wanting to keep your 305 block are for the reasons mentioned by Madmax, you can make power - but you have to choose your parts carefully and realize that will gain less HP/$ spent than if you spent the money on a 350. Just make sure your reasons are "valid" and not doing this just to be "stylish".

 

I actually thought of another reason:

If you are planning on a 383, and are going to clearance the block yourself, may as well practice on the 305.

 

i am jumping on this thread late i considered a 334 kit before for certain reasons but i have extensive stroker motor expierience with haveing numerous 383s,406,(not a stroker) a 415 and a 420 ci strokers i would take that bet with the 334 smoking that 350 engine bet i did some research and found out that 334 will out torque that 350 by about 30 ft lbs and equal the 350 in hp now i am not talking all out raceing here i am talking even up mild street engine just like the tpi is that 334 will take advantage of it and smoke that 350 everytime my only concearn is can he hook it up everbody knows hp will make you fast but tq will get you there first just ask lingenfelter

 

all you need is a 400 chevy crank, rods, ballancer and flexplate or flywheel and reuse or buy new 305 pistons

 

some of the ls engines are less than 4" and making killer power so don't be a hater luve all that's gm.

 

Welcome to the boards...

Set your preferences to "newest posts first" instead of "oldest first", and that way you'll be participating in current discussions instead of re-opening threads that have been dead for 10 years. (for good reason in this particular case)

 

Nothing wrong with building a 305. They can make very respectable power with very good torque. If you do the same tricks to a 350 and stoke to a 383 it will best the 305 build though. Ultimately that's your decision and nobody elses. The people on here are just trying to help you get the best bang for your buck. The power difference between the 350 and 305 "or lack thereof" is due to the 350 using the same intake that was designed for the 305. Pretty well known fact that effectively detuned the 350 from the factory. There really is no replacement for displacement. As far as torque. Considering the same displacement motor the larger stroke motor will make more torque. The short stroke large bore motor is going to make more HP. Given the natural tire shredding torque the TPI already affords with it's long runner design, HP is the element that's more at a deficit.

 

.. LOL! Yes, 4/5's of the postings in this thread are from 2002...

.. Not doing anything but stroking a 305 to a 335 gives an engine with less HP and torque than a 350... especially since the 305 heads have smaller valves... although there would be an increase in compression ratio that would help...

.. Also, the 1990-1992 TPI 305 cars with dual cats and 5-speed were faster than the 1987 TPI 350 cars with single cats and automatics only... so other mods besides just stroking are required for a significant boost in performance... which is another consideration...

 

Lol, I didn't look at the date. Gotta love people who reply to looong dead topics! *cough* Chuck B *cough*

 

Are you looking bang for the buck over you 305 the 350 is the way to go.

Yes lot times stroker dont cost that more to build than a standered 305 or 350.

But I was you a 350 with basicly same set up is going to make more HP and TQ more easy with out more mods.

On the other hand if your' going to build a stroker 383 or 396 but a 383 more common set up.

Bigger the motor you can hide a bigger cam in it if you have to meet smog it helps out.

Get all your ducks in a row make sure you ready to spend the cash dont do lot others done start building it then find out they can't afford to build it and junk the project.

Stick with it you be glad you did when your all done making sure you have emptyed you saving account LOL.

 

I have and I have to tell you when it's all said it done, this thing goes! Yes it's polished in all the right places and while there are always faster cars out there I've yet to really come across very many. Build it right! Get an internally balanced crank and rotating assembly and have it all balanced to the very tightest of tolerances, don't overcam! Don't go for super big compression if you are going supercharged like I did. You would be surprised what "doubling" under the hood does to these third gens! Building hp is one thing but you have to consider building a tranny to handle it, a rear end that will stay together, a tighter lower suspension to stick, frames to be connected ect. Take your time and enjoy building it up and I personally can say from my own experience that my 335 TPI is my favourite engine I have had! PM me and I can give you more build up info if you like.

 

Boost makes anything fast.
9 psi made my bone stock 305 tpi auto go 13.4 at 110 mph. Thats 20 mph more than what a stocker should run

If you are boosting you dont need a stroker 305.

 

Why is the stock air filter box still on lol?

 

That's kinda like saying if you have one turbo, you don't need twins! It really doesn't matter what anyone else says or thinks, it all comes down to what you as an individual wants to build yourself or have built and can afford and what you are going to enjoy. Me personally, my 305 stroker is my favourite over my 5.7 L-98 IROC and I'm in no way saying it's not a nice car or engine by any means just I wanted to build a mini stroker that would run down Giants and that's what this Camaro does. Like I said it's not the fastest but many many times its left 350's and bigger wondering what the hell happened? It's a lot of fun! If your heart is set on it, go for it and have fun doing so.

 

This makes sense. If youre young and starting out maybe seeing what you can get is fun.

How many stock 350s are running around these days to boast about keeping up with? Stock 350 TPI is slow in todays world

Seriously.....get a roller block 350 stroke it HR cam decent set of heads, once you get a feel for what that will do you for youll forget ALL about the 305. Maybe put it aside for the next owner if he cares about it (probably not)
I drove these cars brand new everyone hated it had a 305 even back then they all wanted the 350 as the 5.0 GTs would give em a good stomping.
