I got 5 trucks. One truck I want to tubocharge, has a 454 CI GM motor. I have the turbocharger kit, just have to build a low compression ratio motor. It would only run on high octane fuel or E85. It should make 450 HP without too much effort or expense. My latest acquisition is 1995 GMC Sierra 3/4 ton with a 350 ci small block, it needs a differential rebuild. It was Kansas county maintenance truck. The beauty of the old GM trucks is the availability of aftermarket high power addons. Or just drop in a LSX engine.
