I asked this question in my "Horsepower Post" but didn't get any feedback at all. I had my Edelbrock RPM's cnc-ported..and milled .060,by Jeff at Modern,last Fall. Still have to finish re-assembly of the 440 they're going on. With approx. 35 cfm more flow on the intake..and a bump-up of compression,from 10:1 to 11:1...what can I expect to see in horsepower gains? Thanks! Randy B
