Don I see no reason it shouldn't run very deep in the 10's. My 408 was 10.8-1, solid flat Hughes cam, 727 ran 6.57 @ 3260# on pump 93, it ran 6.68-.70 in street trim.
Cool. You have a good bit better heads than what these are, but i have a 904 and more squeeze.
Be interesting to see.
Plus, your stuff always runs way better than the average bear..... lol
