i have a 4.3 vortec bored .030 over. it is bolted to an automatic tranny and when you come to a stop the engine lopes and the truck will lung foward and if you keep the brake on it will die. someone told me i needed a stall speed torque converter? are they right? how do i find out the specs on the aftermarket cam so i can match a converter to it?

sounds like your torque converter is staying locked up. check you wiring and vacuum plumbing to see if you have it hooked wrong, when you push the brakes its supposed to be disengauged.
if you check out TCI converters they make some that you can have tuned to your application

The torque converter can't even lock up in 1st gear...

Sounds like you have an IAC (Idle Air Control) problem.
