422 dyno fail

Nat said
not much more 613 lift with 1.6 rockers 2.08 valves 10.5 compression , also lost power when i went with a victor instead of a fully ported air crap

What was the duration @.050 and the centerline?

I think that's significant more lift: 613 vs 570? And 2.08 valves vs 2.02. And more compression, 10.5:1. Not sure that compression is going to run off of 91 pump gas. It won't with Calif. blend 91 pump.
