I ran this combo through my engine analyzer. I set the scr at 9.5 because I don't know the chamber size. The cranking compression would be 205psi with that cam at 9.50scr.

Chambers are advertised at 72. Gotta figure ****ty head gaskets unless he goes Cometic.

Which I would. Need as good a quench and compression as possible, especially on the 350.

I have a set of 670’s that we cc’d. Mine are exactly 72cc.

Then I guessed correctly. I went back and calculated using 72cc chambers, 8cc valve reliefs on flat tops, cometic head gasket .030" thick with a 4" bore and zero decked. I raised the compression from 9.50psi to 9.54psi.
