well i think that retarding the cam will up the range of usable rpms (something like that i think). well with my 4.10's and stick, shouldnt i retard it at least 4*?? hopefully someone can shed some info

All I know is that changing the cam timing will shift the engine's powerband to different rpm ranges based on where you move it to. Sorry I can't help more.

The guy to ask would be fiveotony. He runs an E-cam that has been retarded. I think for it being a street car, it wouldn't be worth retarding. You would loose more low end power than you already have, and your shift point would be raised up to almost the 6k range, which is starting to ask for trouble. Tony may say something else, but from just looking at the situation, I don't think it would be the greatest idea for a street car.

as far as I know... for every degree you retard a cam it moves youre power band up around 100rpm. For every degree you advance it it moves it down about 100rpm. You could possibly make more power by opening the intake valve earlier, but I dont know that much about the 5.0 to make that statement.
