It’s pretty hard to make any power from a combo that only has 125-130 cranking pressure.
One or more of these scenarios is probably in play-
-CR is less that 9:1
-cam is rather large
-cam is installed retarded
Imo, a head needs to come off and things measured to determine true CR.
Cam specs need to be verified..... by measuring or by part number.
Or all three, LOL.My first step, in a few weeks, will be to pull the intake and heads to measure actual CR. I do know for a fact that when my buddy put the cam and heads on this engine he just stabbed the cam in and didn’t degree it.
