Build Plan Questions
I was looking at the Ford Racing GT-40X heads. If the rest of my engine is completely stock, what type of gain am I looking at? Also, with drag radials, Flowmaster 40's, 3.55 rear gear, h-pipe, long tube headers, silencer box delete, and advanced timing on a manual transmission car what kind of time would you guys assume it would get in the 1/4 mile w/o and with the heads. If you have any more tips, i'm open to all suggestions.
