quick CR estimate on KB107's

a SP manifold, 750 carb, 3000k converter, and a 292/ 292 with about 500~ lift. Too aggressive for a street/strip machine on 91 octane?

This combo on my last engine which was a .030 360 was a nice street engine. Though I moved to the Air-Gap later.
The above posters, I agree with. Though I had ethier 89 or 93 to deal with. It's good to see them speak up on it.
