This would work for 3,000-6,500 on motor, and run past that with a 300 shot.

685/620
258/268
108

Morel 4603's with this cam will need 220# seat pressure. Lifters in stock cam would take a few days to grind.

Not if you want it to run. The last BBC I did has a 300 shot on it with a 109 lobe sep. She makes 1160 NA and 1490 with NOS.

BTW, this will only require 145-155# on the seat, and 370-380# at max lift.
