4.060 bore, 3.58 stroke, 6.123” rod lenght, 10.75-1 static compression, IVC ABDC 41. I recalculated static compression ratio and came up with 10.57-1 SCR, still 209 cranking pressure vs. 211 at 10.75-1. Heads were Cc’d at 70 by my machine shop. If I’m doing something wrong in calculating these numbers I’d be glad, as I’m not thrilled at this much compression. As a refresher for those that don’t read the whole thread, the block was decked .095 and I have a true flat top with no valve reliefs and .005 piston to deck clearance.
