I agree but how far off does it have to be to be THIS bad?
A loss at high rpm would mean the cam would have to be WAAAAY advanced, right?

I had a 318 in a 74 Duster that was an absolute PIG out of the hole. It would not even peel out on gravel. It ran smooth as glass, quiet and nice. I swapped distributors, carburetors, spark boxes, I cranked the static timing to the moon...nothing made any difference worth mentioning. I pulled the timing cover to see that the cam sprocket was 2 teeth off the mark retarded ! I replaced the set since the chain had slop. Once back together, it would peel out easily on pavement and ran just as smooth as before.
