I have a 99 Z28 with 3.73's and a 2500 stall. Iwas told that I can't go much past a 224 came with this stall. I'm trying to figure out if that will get the job done or should I bite the bullet and get a bigger converter? I will get heads an dintake later. I'm looking for a quick street car that goes to the track, not the other way around.
