I talked to a GM Preformance rep the other day and he has given me an idea. The plan is to dump my 4.8 for the Gen III LS6, Z06 vet. Now i want to stick twin turbos, if possable, a 100 shot of NOS on top of it. Now to the question part of this. I know the factory 4L60E will not hold with that much horse, so is there a trans that will back it up or is there a rebuild kit that i can get my hands on for the 4L60E? ALso if i get past the trans issue, How the hell am i going to make it hook up? Finaly I fear that the carrier bearing will not take the abuse. If anyone has the solutions to let me know, thanks guys hope to hear for ya.
