I have a Keith Craft built 482 w. a Shelby aluminum block that closely resembles the configuration listed by Xracerbob. 604 hp with 620 or so ft. lbs. of torque. I have a build sheet from Keith that lists the details on the cam. It has Edelbrock Stage II heads, Quick Fuel carburetor, Comp cam, MSD ignition and Avaid pan. I am losing a little
oil pressure on modest curves such as you might find on a cloverleaf exit or entrance while running a very reasonable speed, so I am somewhat concerned about that. I might advise checking into an accusump (55psi drops to 40 psi with no corresponding drop in rpm).
