okay my 440 cam flat spot on a cam lobe why does that happen. it was fresh motor with less then 8oo miles on it it was a mopar performance resto mod cam. my next question is my car has 346 heads 10.1 compression i wanna put a bigger cam in it i liked the resto mod but i wanna little more power this is a street car any suggestions.



What were the specs on the resto-mod cam? Since you have a little experience with THAT cam in YOUR set up use those specs as a baseline. You know you want more cam. 10 degrees additional duration will net a noticeable change in the powerband. 20 degrees is a BIG change.
More lift means more flow, to a point, and will make more power. Modern grinds can get you the lift without a bunch more duration.
