Im running a Carter 625 with mech. secondaries, with the Comp 268 cam.......Love it!!!! Plenty O torque...even when I was running the 351M. I've since stepped up to the 400. No disappointments!! I first did this swap back in 1988....no regrets, even if I did lost 3m.p.g. The funniest thing was one night I was wheelin in some sand dunes and this guy was stuck down in a bowl cuz his LS7 threw all the belts, so Im a Dude and pull him out. Then He asks me if I'm running a 390!!!!! Said, "Nope...its just a little ol 351M!!! I got the strangest look
