thanks, my engine is stock as hell. i did figure out how to get the numbers i need, but that is alot easier for sure. ive been working on it, and i think this program is pretty damn accurate. now all i need is stock cam specs. im set up with a 268/268 right now, but i want to put the stock cam in there, but i need either the intake or exhaust centerlines to input the data correctly. by the way, does anyone else out there use the new dynosim?
