19Iroc-Z90

I am new to the page. I have 1990 Iroc-Z 5.7L. I have a Comp Cams 08-302-8 cam in it. I was wondering what torque converter I should go with and what brand?

Thanks

Depends on what you want. I have a 3000 rpm converter on mine with 3.70 gears. But it's a built transmission and I have 350 HP at the rear wheels. If you are running stock heads and TPI you should probably stick with 2000 (S10 converter) or 2500.

Frankly I wouldn't go lower than 2500 if you want to notice any significant improvement. I have a 2500 rpm in my TH700, 3.42 axle, modded ZZ4 with probably 420 ftlb of torque, ~3300-3400 lb car, and it'll flash to about ~2300 rpm.

But during normal driving, it drives completely like stock to the point that you'd never guess it has a non-stock converter in it.

That cam is only good from 1200-5200, something close to stock will do fine. At least get somewhere into the power like 1800-2000 converter

whatever you do ditch the heavy 12 inch

id go with a yank SS Series with a 2800 stall

S10 converter. You send $165 and you get 2300+- stall

2800

S10 converter is too tight IMO. They creep forward with a cam and a little higher idle.

I agree with them being a lil tight on a "cammed" engine but tbh his cam is a very mild one, not much of a cam at all. I figured it would be a good fit. Maybe a 2800 would be better though.

No one bothered to ask him about the rear gears he has, be nuts to run a stall on a street driver with 2.77's. 2,73's, eh?

it says 3.73 under his name

not at all imo. It helps all cars

in fact my bolt on ls1 with 3200 was only .07 faster with 3.73’s vs 2.73’s, no other changes. Im sure some transmission tuning of the shift points could have optimized it more but 60 foot only was .05 better. Hardly a gain.
