Hi im planning on building a 335 stroker bc i wanna keep my car with the orig engine and im not making this thing into a drag car jus some fun...but im curious as to what kinda power 335 can produce?...im more interrested in TQ gains as that where the fun is ..and i know a 350 is cheaper and better to make power but i wana build sumthing different because i already built a 350 previously

1991 roller block
335ci 10.3.1 compression
fully ported/worked LB9 heads
stock auto car Cam with 1.6 roller rockers
slp runners

any flywheel power guess's?
thank you everyone

btw i browse this website all the time and this is my 2nd acct with TGO so dont mind the 1 post lol

i don't know exactly what a 335 can produce...but i do know a guy on here attempted to go all out and build one on here years back just to be different, and at the end of the build he had sank tons of money into it and ended up disappointed and was even telling people not to bother with it and to go 350 or bigger. if you do a search you'll find his postings i'm sure...not trying to bash on ya, just trying to possibly save you some money...

Stock base? ported stock base? How ported are the heads? still a 1.84" valve or upgrade to 1.94?

Stock auto 305 cams were tiny i believe. I'd swap it out and put in a L98 cam or Lt1 cam atleast!! With one of those cams it should be near 230-240whp, run bottom 13's.
One guy here made a 335 TPI and it was around those levels.

yes, you're right. he had like $8-10,000 into it to have...the performance of a near-stock L98. he was utterly disappointed. I'm gonna do some searching because I think the OP needs to read This Guy's thread...Its eye opening...

edit, this isn't THE thread, but its one with a lot of info on the "venerable 335"...

Its ok to build it to be different, and as long as you dont expect it to make big power numbers. It will make decent torque but still be down on power compared to the 383 you could have made with the same crank in a 350 block.

I built a 331 out of a .030 over 1991 roller 4-bolt 350 block, a 3.25" stroke crank (using a two piece to one piece rear main seal adapter), 350 rods, 327 high top pistons, balanced bottom end, 65cc truck heads milled .020, LT4 hot cam, and a ported '85 Corvette TPI system with a Megasquirt 1 EFI controller, 36lb/hr injectors and a 4-pin HEI. I'm currently producing about 325 hp with stock exhaust manifolds and a 2 1/4" exhaust. Including parts and machine work, I'm in about $2500, including buying the long block. It's torquey as all hell, and even with 3:23's and limited slip breaks the rears loose at will, and will put you in the seat. My next upgrade is Vortec heads and a new lower intake, LT4 valve springs, headers with a 3" exhaust system, and full roller 1.6 ratio rockers. All this should easily bump my output to around 400 hp and 460 lb ft of torque, according to Comp Cams dyno calculation tool (which has been found by several magazines to be extremely accurate on builds, even conservative in its estimates).
327s are fun little strokers, especially for street cars, and spin up very fast. True, they don't produce the high horsepower numbers that 383s do, but they make their power very quickly and down low, where a street car utilizes it.
Note: A mildly ported TPI system is more than capable of feeding a 327 throughout the powerband, whereas a TPI would have to be greatly modified to adequately feed a 383 in the upper end of its powerband.

TunedPort335 is the guy to search for. Had some decent results. Ran mid 13s with a pretty stock top end. I think?

1983Chimaera-- That seems like a mismatch with the short stroke motor and TPI. But if it works it works. Get that exhaust and other mods done and it should really be fun.

YES, TunedPort335...i couldn't remember his name...had the red Camaro with the ghost flames...right?

Thats a bit of a different direction. The common 335 is a stroked 305 block and wouldnt be as good as your 331. The bore size on the 305 is a handicap. You're limited on how much head flow you can get through the smallbore since valvesize can only be so big on a 305 bore. A 350 bore can take 2.055-2.08" valves and make big numbers. You cant do that with a 305, they can only get to about 1.94 in most applications, and maybe a 2.00" in limited lift motors.

Actually it's a perfect match, and why I went the 327 route. The long runners along with the throttle response of the TPI and the low end torque created by the short stroke make for a very quick revving and fun car. The 331 is also well within the airflow abilities of the TPI system, unlike a larger displacement, so it feeds well throughout the powerband and into the higher RPMs.

That makes sense about the smaller displacement. You have any track times?

Still just a daily driver for now. Once I get the headers on, vortec heads and LT4 springs upgraded I can take it and get a time slip. Until then I still have the less than optimum stock springs on the heads for the LT4 hot cam's lift, and might break something if I try a hard 1/4 mile run.
I did get the exhaust changed over yesterday to the 3" one out of my wife's IROC project car (a factory stock LB9 305 that the previous owner put a ridiculously oversized pipe on), but until I can afford to get a Y-pipe custom made for my headers I'm stuck with her manifolds. My old exhaust was the highly restrictive '83 Z28 2 1/4", but it had finally developed a blow out in the bend above the rear axle last week, so out it went. Hers will get a replacement one of the proper size once I have her engine back in.

Nothing wrong with modding a 305 - I did that with my last car. SuperRam, 268 cam, 1.6 roller rockers on S/R iron heads. A Procharger P1 really helped too . It made 415 rwhp, had it been tuned with the proper size injectors it would have made 450+.
