Hey guys, new to the site, got directed over here by one of the performancetruck members. This site has alot of info I could use and seems like some pretty cool people. I have a 1998 GMC Sierra Z71, has alot of mods right now but the best coming with a 2002 4.8 swap(for now, plan on boring the block out, forged pitsons/rods, 5.3 crank, afr heads, cam etc) with a small cam (.517/.525 on 1.7) and 241 Corvette heads with Z06 valvesprings. I'm building a custom single turbo (Super T70) setup on it and plan on running 12psi on the stock 4.8 (has head studs in it, and the lower compression + alky should cover it with a good tune, parish ran 12psi on pump fuel on a BONE stock 4.8 so I know it can be done). Figuring close to 450-475 rwhp, then whenever it blows should be looking for lots moreMy main project is my 69' Pontiac Tempest, but it's kind of on hold while I finish up the truck. Here's a pic of it before the new rims/tires (these wheels/tires for sale in the FS section)
