I combined this cam with Comp's new Bee Hive spring's & titanuim retainer's. (Ultra-light Set-up)Man, I would recomend those spring's to anyone. They sure helped bring the RPM cabability up on my 408, which is a hard thing to do with a Hyd. Roller engine.
I left the hardware in the "R" heads, went with crane drop in lifters, zero lash. We pulled to 6800 on the dyno with no hint of vavle float. Good luck with the dyno, make sure to post #'s It'll rock
