That combo looks really strong Jeff and should be a complete hand full on the street. graemlins/beers.gif I'd suggest the following hydraulic roller grind from Lunati. It's the same cam I use in the 502 and it pulls very hard.

Part Number 54899 - Grind RRB1-245-250
245 intake - 250 exhaust duration @ .050 lift
.648 intake - .648 exhaust lift w/ 1.8 rockers
LSA of 114 degrees

When do you plan to have the mill finished up?
