The first link SCOTTYINWV definitley had a lot of good info, thanks for that. Helped me understand V.E. much better, and I now know the 620CFM TBI would work with the combo I suggested, which the entire combo basically follows the guidelines in that link. Only thing it didn't really touch on was modifiying pistons/rods/compression ratio. I also found the idea of a GM Vacuum adjustable regulator interesting. Where the PSI increases with Throttle/RPM. Seems as if it would correct a little of the issue of having a rich idle if you crank up the fuel pressure needed with mods. But I'm also reading a little bad about them, such as delayed throttle response due to the vacuum not being able to keep up. Anyone have any experience with these vacuum operated regulators?
