450 - 500 hp 302, all motor

[rtz]

I'm going to need to rebuild my motor though in the near future because of high miles.

All motor would be cheaper then getting that twin turbo kit. Plus turbos get too hot in the summer when it's 100 degree's out and I have to drive ~20 miles to work every day in that heat. The twin turbo's make the car hell to work on and I don't want to have to install them. Changing my spark plugs or changing out the header gaskets with it looking like this?



I can pick up a rebuilt shortblock fairly cheap. Just need a good set of aftermarket heads and a cam. Pick up an intake when I find one. 30lb injectors, and the required mass air, 155 or 190lph intank pump.

Shorty headers, hi flow cat X pipe, FlowMaster cat back.

Run this T5 till it blows up, and 3.27's.

Can I expect 11's out of that combo, or "just" 12's?
