on a fresh rebuilt motor(302 now 306), does it have more compression before or after break in ?
I have been playing with my timing and at one point had it way over 14 deg with no pinging, ran great just did not want to cruise very well, so how did I get away with that unless my compression is low do to engine only has like 30 miles on it ?
