Miami,

Given what you have, I think the most economically significant change in power you could see would come from changing your cam. Adding a hydraulic roller cam and roller lifters is relatively simple, and the horsepower gains are pretty impressive. Those folks with Desktop Dyno can tell you.

Comp Cams makes a retrofit part for the 351W that allows you to use a roller cam in the older blocks.
