Well im building a 335 stroker kit and i was wondering what i could look forward to getting time wise.

completely redone block bearings,plugs...
Powerhouse 335 stroker kit (10.1 compression)
World torqer 305 heads
Comp cams valve train. (244 DUR,) (.501 LIFT)
1.6 magnum roller rockers
3.73 gears
Drag radials
700r4 tranny- trans-go shift kit, Corvette servo.

Then a stall havent got that yet.

I would like to know what I would run with this. But then im thinking about putting my n2o kit on it, only a 100 shot just to see what I could pull off.

If you had to give me a rough guess what would you say??

 

2-3 tenths and 2-3 MPH slower than what a similar 350 would make.

 

But i already have a 350 tpi in my 89 GTA.

But the 91 has the 305 so im gonna build the 305.

Also would it be a good idea to drop in a t56 6-speed??

I need some help, Or maybe some more ideas. so tell me what you think??

 

I think you're wasting your money with a 335.

 

That's hard to say because there are a ton of variables to getting a TPI car to run with that many changes. Do you tune your own proms?

 

Yes my prom will be tuned by a friend.

Does any one have any #'s or what you think.

If you were to purchase the 350 stroker crank then it would just drop into the 305 block with stock bearings (depending where you buy the crank from)obviously go forged with some hyped up connecting rods, if the project is found out to be a loss pull the rotating assembly out have it magnefluxed crank and connecting rods turned what ever is need to clean them up and drop them in a 350 block, your loss would be time, the 305 stroker pistons, gaskets and the dreaded machine shop

not a complete loss but the biggest invesment will be saved (crankchaft)

 

With a good stall and traction i can see mid-hi 13's

You have too much gear for a tpi setup though. and your going to need to open up that tpi to run those times so get out the old dremel.

 

I have already ported my intake and plenium, And I have slp runners.

Ok here is everything that I have.

335 stroker kit
world torqer 305 heads
comp cam
1.6 roller rockers
drag radials
3.73 gears
pulley's
trans go shift kit
corvette servo
msd coil
AL ignition
Edlebrock tes headers
flowmaster 3" pipeing
air foil
t/b bypass
160 stat
ram air intake
slp runners
Aluminum driveshaft
100 shot
afpr

That is all that I can think of at the moment.

If that helps.

B/c i think mid to high 13's is a little high

I was guessing lower that that. like mid to low off the spray. But can you give me some more info on what you think???

 

Agreed .

Your motor will be a low RPM bruiser but will suffer horrendously up top. Stricken by TPI is one thing but the small bore combined with a larger stroke further exposes the stock valve shrouding problems with the small 305 bore. I would find a good used roller 350 bottom and start from there. In the end I you will likely spend less money that way.

 

That might work if the 335 and 383 cranks use the same casting, which they may or may not. A 335 needs less mass on the counterweights to balance the pistons. All that weight would have to be added back to rebalance it as a 383. At worst, if the 335 casting is lighter than the 383, you could be looking at adding mallory.

The crankshaft isn't the biggest investment, anyway.

 

I was thinking n/a high 13's. Your gonna have a good amount of low end grunt so make the most of your 60' thatll make a big difference

But im sure your fully aware and decided to do the 335 thing anyways.

 

Well what can I do to help my top end?

So pretty much from what i have read, the car is gonna be a monster off the line but suck later on down the track.

 

Ditch the 305 and put that stroker crank in a 350 block like any sane person would do. Then bolt on a Super Ram or Stealth Ram.

 

cheap = drop in 350 convert to carb, expensive = convert to LS1

 

you could always find a smogger 400 and run the same times for about 1/3 the price.

 

I was going to do this with my engine but ended finding a great deal on a 4 bolt main 350 so I went that route, but yeah man I'd go for it, you might want to go with like a 3.23 rear gear that may give you a little more top end and won't really sacrifice any torque from the torque monster you're building, good luck man!

 

A guy around here turned his 305tpi into a 335 stroker and he has it running mid to high 12's. I'll see if I can get his video on here.

 

Here's this stroker TPI motor. http://www.cardomain.com/ride/262003
One of the chevy magazines did a feature on the 335 stroker but I can't remember which and how they fixed the obvious top end problem.
