Hey i'm having my tranny rebuilt and i was wondering if i should get a stock converter put back in or an aftermarket higher stall? Its a bone stock 99 z28 with 2.93's what speed stall can i go with an aftermarket so it locks up at curzing speeds?

 

I'd go with a lockup 2800 vig converter, but that's if you have the money to do it. Whichever company you go with, make sure it is the lockup kind and a 2800-3200 would be good for a stock car.
