To answer your Question: The exact cam I really loved is a custom grind. Here are the specs. Advertised is @.0045"
Adv. Intake 276 .050, 221 , .200, 132 lobe lift .3027
Adv. Exhaust 284 .050, 232, .200, 143 lobe lift .3273
ground on a 112-113
The exhaust lobe is a little aggressive but it made 7 more HP than an alternative slightly gentler exhaust lobe I will list below. We had to run the stock "093" heads which have small valves and poor stem angle. The exhaust flow is especially poor with the required exhaust manifolds. That cam really helped.
The alternative exhaust lobe, which is more gentle and popular, would probably work fine with the later heads. It is:
Adv. 286 .050 230, .200, 139 lobe lift .3027
These cams were easy on the valvetrain. I ran a 276/286 in a 421 HO 9 passenger Catalina wagon over 100,000 miles. Pulled a 19' Sea Ray probably 10,000-15,000 miles over many years to lakes all over OH, KY, TN. That wagon weighed 5050 Lbs. It ran 14.60's all the time with that cam. Turbo 400 and 3.42 rear.
