What are you looking to do? On these vehicles I would recommend a positive displacement supercharger especially if it's going to be a street cruiser. The Roush kits and Edelbrock kits are superb to start with. The Whipple Kits are great too but to make decent power you need to get the H.O. kit which is expensive but makes great power at 550 bhp but I"m not thriilled running dual pump setup on street car. The base Edelbrock for example makes a fantastic 465 bhp don't require fuel pump upgrade or hacking into wiring.
