i have a 73 Jimmy with a 350 in it. I need more power because i want to put 38.5's on it and the stock 350 won't get the job done. some people have told me that a supersharger would be great because of the low ratio and i could save later on gas that way. But now i desided to go to all of you for the real answers. What superchargers are good for my car if any? what other things can i do: headers, ignition, what? i already have a four barrel Holley, but that is about it. I need some pointers hear from the people that have done it before. thanks.
