360 Crate Engine enhancements
Thanks guys. So it sounds like there might be some options for a better cam for my setup, i'll start researching that.
The heads are stamped R/T. I believe the R/T heads was the difference between the 380HP and 390 HP version of the crate engine.
I have thought about trying an AIR gap, but havent pulled the trigger yet. I have also read in other threads to try a 4 hole spacer on my M-1.
