My plans are to build this into a economical street strip ride with a mild 440 with a 75mm turbo.

My ?'s are, can I get fiberglass bumpers roll pan for this? Or use car bumpers? I plan to get a hood too. Any other ways to lighten it up without butchering?

What are you truck guys runnning for rear suspension and tire sizes without moving the frame rails? Pictures would be great.

Initially this truck is just going to get a low mile motorhome 440 with 440source heads, a single s475 75mm turbo with a turbo rv 440 manifold. But yes it will be blow through.
