I was wondering if anyone could give me a clear, concise description of how to calculate stalls on aftermarket torque converters, their applications (street/strip) and their practicality. I am searching for one to put in my '68 396 without losing streetability while at the same time improving performance and dropping et times. The new convertor will be bolted to about 400 horsepower if this helps in the calculations. Thanks.

John,
I am sure that someone somewhere has some type of system to calculate this, but until I see it, I think the best thing to do is to call your converter manufacturer of choice and let them recommend what to use. There are many variables that influence coverter choice . Car weight, rear gear, engine size, torque and hp, camshaft, it goes on and on. The people that sell converters want you to be happy so they will steer you in the right direction. Everyone else is just guessing.

i have a small block in my 68 (406/400hp) and use a 2500 stall,it is a street/strip car and i didn't want to lose streetability,all stalls are app. and are a general guideline,depends on torque .
