Like the title suggests, just how far out of the hole is considered TOO FAR on a 454 Mark IV that will see marine use? The motor is being built to chug-a-lug-along and won't see much use past 5500rpm.
Before I owned the boat the engine builder knocked the deck height down to 9.766" --- With the new 4.25" stroker crank, 6.385 rods, pistons, the piston will be approximately .014" out of the hole.
Assuming there is sufficient clearance for the piston to the cylinder head, is .014" too far out of the hole for the sake of the piston and ring seal? And if .014" is too far, what's the best route to take to get it with a tolerable height? Custom piston? Shorter rod? Different block? I'd rather build this right the first time than put it all together and then next year have to dig back into it again because I cut one corner. But if .014" is AOK I'll run it and keep my fingers crossed.
