Nice numbers! I've been thinking about the race version of that cam for a while now (the one with .630 lift, same duration)...but I'm having a hard time pulling my little cam out that works so well. My engine is very similar but with a smaller cam, 410, 10.8:1 comp, stage 2 ported Eddys by Shady Dell, 750dp, victor intake, Comp cams XR286R (248/254 duration) 3200# car....not sure on power numbers, but I think I'm probably in the 550 range. The car runs mid 10's and picks up milk and eggs from the grocery store too :D.
