I would be a little hesinant to put a supercharger on a car with a stock rearend and suspension. It is a general rule of thumb to build the base of the car (suspension, rearend, tires) before you get into the power category. You probably meant that he could do both when build his supercharger or engine but just stretched over a longer period of time.

The rear can handle 350+ hp from a centrifugal SC. 2001+ 7.5" rears have 28 spline axles.

Since the power doesn't come on until 3000 RPM, there isn;t as much stress on driveline components. (If you try and launch with 3000+ RPM drops, then you're in trouble.

If you're going to use a SC, you should keep stock gearing. anything above 3.55s will slow you down.

If you're going Naturally Aspirated, gears will definitely help.

yeah, do the rest piecemally after the big ticket items.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
