I bought a 1998 4l80e and I would like to rebuild it to hold 600hp. Can you guys recommend a kit that will b have everything I need to rebuild it? I've been researhing it but I see so many not sure which one to get.

Info on my truck
2000 Gmc sierra reg. Cab

lq4 I believe the longer crank sticks past the rear seal about an 1/8"

72mm turbo

60# injectors

also a good torque convertor with a 3000 stall with balloon plate.
