I swapped out a -3 for a 3X and also swapped the carb from a 1050 dom (9375) to a Pro Systems 1200cfm. On a .720 (gross) lift 11.5:1, 4.50 bore 528, It picked up 3 tenths and 4 mph. I was using the 572-13 heads, I was more surprised than anyone shruggy cool
I'm only using the EZ heads and probably a .600 lift cam and a 1050 dommie.
