Thanks Fishmen. I have a FBO limiter plate but I have adjustable distributor so really don't need it. A very smart guy who lives near me and used to race pro stock hemis took a look at the motor last month and took car for spin and said it ran very nice. But first thing he said was to run 38 total. I was at 35 at the time. I'm gonna try 22-24 initial (maybe more if I can get away with it) and 38 total.
