    6.0 swap. Anyway, 1500 on the super charger or 1500 before the supercharger?

    Are you wanting to have that much power at the wheels or flywheel?

    if you plan on getting a supercharger just do the exhaust for now including y pipe or long tube headers. get a tune after you get the supercharger.

    cam it and add a stall, gears, intake,pullies, headwork, longtubes, custom tune. then later add the supercharger. you would be around 280-300 to the wheels and should be a fun truck.

    Well I already have intake and exhaust and I was thinking of ordering a tune from nelson wheatley or black bear.

    Would the supercharger/Turbo blow my engine with stock internals?

    Made to fit a stock engine. Now it you want to push 20psi from a twin turbo set up, yeah you probably want to build the bottom end a little. I hear there's this really neat SEARCH feature that would probably help you here.
