The car is a weekend car with 3:73 rear end gears, four speed Trans and power brakes. The car is also equipped with a set of Doug's 2" headers coupled to a 21/2’ flow master exhaust, a 750 speed demon carb on an Edelbrock RPM manifold. Any suggestions would be of great help.

Pat McCarthy is the resident BBC expert here, but until he shows up, I'll take a shot at it just for grins. I have to assume that if you're runnin' pump gas, your present cam is probably closin' the intake valve at around 49 degrees ABDC and usin' a 0.050" duration of about 246 degrees.

To use a solid roller and maintain approximately the same characteristics, I might use a cam such as the Crane 138601. It closes the intake at 48 with 246/254 degrees @0.050", ground on 110 LSA.
