So the caps are being machined at Straightline Machine LLC right now. Just did a test fit of the first cap off the machine on a stock 330 MD block I got here . How much material would you guys like left in the bearing journal area? .005/.010/.015/.020? I can change the cutter comp and adjust it somewhat. I’m also wondering if I can add the reliefs for the bearing tangs for Cleveland and FE to the cap, I think they are located differently. First batch only had the tang relief for FE.

.010" undersize for the main bearing bore is about right for most shops with line boring equipment...
