Im in the middle of a frame off restoration on my 64 Bel Air and will be putting a 4.8ls with less 40k miles in her. I want to do a single turbo setup and will be running a th400 trans. I have followed a few similar build threads but could use some guidance. My goal is 550rwhp. I need some help deciding which turbo, piping, stall, wire harness, intercooler, and mounts to use. This will be driven on a weekly basis and falls in the "pro-touring" style build. I will be using a stand alone harness and the motor has electronic throttle that came stock.

I know trucks are gay but I'm running a fairly stock 4.8L in my silverado and just got some dyno numbers on it this week. It made 578rwhp and 547ftlbs through a 4L80e with a cast S475/83 on 12psi. Your goal of 550 is easily attainable

I would say 2 to 2-1/8 hotside piping and a borg warner s475 t6 1.10 ar.

Will this be 100% stock? Id suggest getting a cam and springs.

Yes, cam and springs will be changed.
