Okay guys I'm building an 02 Sierra this summer, rcss, z-71, I already hav a 14blt rearend, I want a 6.0 stroked, I don't know if that makes a 408? Mid grade heads and cam, with a 4l80e with a badass shiftkit, and a good torque converter, planning on supercharging but that's a different phase, so minus the supercharger and labor how much money in parts do you guys think?
