Bobby, don't listen to these guys, here is what you do first rob a bank and fatten up your bank account. Forget about the intake and exhaust that will just tease you and delay the inevitable, first off pull the block and bore it to 5.0 liter, well since we don't want any regrets might as well go all out and bore that hunk of steel to 5.5liter, throw some forged pistons, Chevy rods, 3 angle valves, cams, etc... the works!! Then your ready for the real juice.....introduce that motor to the Supercharger, yes that's right airforced induction at it's finest a massive Whipple twin screw supercharger, and boost away, and if you are still not satisfied throw a couple of nos bottles in the truck, fine tune it all and hit the gas and watch your car either blow up or fly like a jet. Good luck-
