372or 416 and why

earth, I'm not a fan of having a lot of cooks in the kitchen... ya know? What is decided to be done needs to be your decision and who ever is doing your machining/setup. Everyone does things differently and most times the same result can be gotten a few different ways. I'd wager the whole package is currently a mismatch. But what needs to be done is a matter of opinion and personal taste. If you are using Bobby, rely on him to get your combo matched. It's obvious there are some rather large issues with the combo, so I'm sure he can improve it. I have run 185psi with iron heads on pump unleaded high test. But your tune needs to be dead on.
