For a heavily controlled race car with a SBC what clutch and why?

Has to run a stock flywheel, is a 26 spline T5.

try a tilton 5.5 inch racing clutch. it should work.

"Heavily controlled"...what does that mean and how does it affect the clutch options?

Engine is 10.1 compression, max power 237 hp max torque is 307 ft lbs, 3400 lb car.....if its not in the rules you cant do it....heavily controlled/strongly regulated, poor choice of words maybe

So if it's such a wimpy engine, why not just get one from your local napa or rockauto.com? No point in spending any more than a stock clutch costs if it won't yield you any gains.

I am looking for endurance and longevity.

Most race clutches are made for ultimate grip and to handle higher RPM with longevity as a secondary consideration. So I'd avoid the 6 puck etc type clutches.

The more surface area you have, the better a clutch will grip leading to less slip and thus longer life.

For those reasons, I'd go with an 11" stock type clutch, assuming your flywheel will allow that. There are stock Chevy flywheels for pickups that should allow for an 11" clutch.
