Need some recommendations for a camshaft: Should I stick with the .509MP Camshaft with Edelbrock 84cc Heads, or go to a larger Hughes Flat Tappet with .569/.576 (1.5) lift? Desktop dyno is stating a gain of only 15 peak horsepower. Recommendations? I am talking to Comp Cams as we speak. Thanks in advance. Comp Recommends .545/.545 camshaft.. I'm showing on Comp Cam Quest a 17HP Peak difference between the two camshafts at 6,000RPM. Seems like a lot of hassle to build an additional 15 horsepower or so?
