Thanks for letting me know of your experience. I bought this cam from another racer that never used it. It came in a package deal with my B1 heads, intake, valve covers, valley plate, etc.
I measured the lobes using a dial indicator type follower with 0.810" dia. My roller lifters (Comp 892 offset seats, pushrod oiling) have 0.800" dia wheels. If the dia is significantly different, it can change lobe numbers slightly.
Both intake and exhaust measured 1-2 degrees more than the cam card. I actually measured 5 intake and exhaust lobes (different cylinders).
