So my 03 sierra is pushing 80k and since i'm planning on a ls6 w vortech swap (hoping for about 650hp to the flywheel after all is said and done). I want to go ahead and build the hell out of but i really want to stick with a stock stall since i still drive it everyday and tow often. Any links or advice would be great, thank you in advance you guys always come through with great advice and help once again thank you!
