Re: 5.7 Vortec basic upgrades
Did something similar to this. Planned on putting a different engine later on down the road and wanted something to drive around now.
Bought a 97 Suburban to part out.
I put a HEI distributor on it, carb manifold, Quadrajet, headers, and exhaust (most of the exhaust system was missing anyway).
Even with the 3.07 gears, ancient Turbo 350, and an engine that had 240,000 miles it felt pretty good.
