you will need more compression. the s/r gm engines have 8.5:1, so by putting 64 cc heads on it i think you will bump it up to around 9.1-9.5:1. you will want more compression that that with a decent sized cam and nice heads. i would say if you have the trick flows shaved and are at about 10:1, maybe 375 horsepower and low 13 second 1/4's, maybe faster and more power even.

and even if it is a WC t-5, you will chew it up and spit it out with that much power.

how much difference in power will it be from 9.6:1 (that is what a technician at trick flow said) to 10:1 compression?

WHAAAA????????

No way he's going to wreck that tranny unless he's beating it like a red headed step child.

I'd put that car mid-high 13's because driving it is going to be a trick.

ever wonder why they never put any t-5 behind a 350 dip****?

i know a lot of the better flowing aluminum heads like a lot of compression, my friend has the trick flows with 10.1:1 and he runs some very nice times. whats the point of aluminum heads on the street minus the weight reduction if you dont take advantage of the fact that you can run more compression without detonation.

You can run 10.5 with alum. heads, more if you run alot of duration and valve overlap.

Now now junior, don't get all excited on me. I've seen plenty of T-5s behind 350s. I've also seen them behind turbo 2.3s and pretty hefty 302s. Unless he's a powershifting-clutch dropping-slick burning-mad-man I don't think the World Class T-5 tranny is going to just scatter parts everywhere driving down the road.

Ah kids, what are you gonna do?

um yeah your own link says max of 330 ft lbs of torque and 450 horsepower if not drag raced. he plans on taking it to the track is all i am saying. most people like to go more than just a couple times.

Metal is metal. It says hardened gears and steel bearings. I bet your six specs out the same way. Besides there is a difference between rated and actual. A 1.5 to 2.0 factor of safety is always engineered in. As long as he runs on street tires it should not be a problem. I'd be more worried about that 100K + mile 10 bolt letting loose before the tranny.

You are right though. If you race long and hard enough on something it will break. I guess we'll just have to see what happens.

Speedemon171

i don't plan on drag racing that much. And i sure as hell know not to use slicks with the 10 bolt. As money comes i will be upgrading. Right now i just want to drive it a little wild and not have $h!t blow up on me.

Car craft did that exact same buildup ("Worst-case scenario low compression smogger 350") with the exception of the headers about a year ago. Got 415HP @6000RPM WITH ONLY 9.1 COMPRESSION! The motor had a very broad torque curve too.

Put some DR's on it and it should be good for at least a 13 flat. I'd bet on 12.6-12.7 with a decent launch.

Speedemon171

i'd defiinitley need a new rear to use drag radials. My rear will go Boom with any sort of severe launching.
