I have a 451 with 13 to 1 C/R, 915 heads with larger 2.14/1.81 valves. It currently has a 509 cam which has 292 duration, 242 @ .050". And .509 lift. I am thinking about going to a Comp Cams mechanical cam. The 23-232-4. It has 282/290 int/ex duration, and .520/.540 lift. And 244/252 duration @ .050". My question is: will this cam offer much more in power output than the 509? It isn't much more in lift and a little shorter in total duration. Although ex duration at .050 is 10 degrees more. Anyone have any experience with these 2 cams? Thanks.

I have heard that a mechanical cam will out perform a hyd cam with the same specs. I suppose thats due to a more stable valve train. Could I get good results by simply just using solid lifters on the 509 cam and setting valve lash at .005" or .006"?
