Vortech makes a supercharger kit for the 302/351. I know a guy that put one on and said it runs like a rocket first few miles until it heats up. needs an intercooler. I am nothing but pleased with my 300 turbo setup even with my rather primitive boost referenced fuel regulator .For some reason , that mushy off idle throttle response common with these engines even dissapeared . The hardest
part of the project I thought was fabbing up the exhaust manifold out of weld els . Also trying to determine the right sizes for pipe diameters was confusing not being an engineer. One mistake I made was the 3/8" oil return line. Keep it 5/8 or 3/4" the first time unless you enjoy dropping the oil pan. A good book is Corky Bells Maximum Boost, it has invaluable info for designing a custom setup.
