Anybody know what the piston out of bore distance would be with an Eagle 4.00" crank, Eagle H beam 6.123" rods and Ross pistons with a comp distance of 1.459 "? How would you figure this out? Trying to figure out how to come up with the optimal .035-.040 quench. Isn't the normal 340 out of bore .018"? If not then what is it? Thanks.

Take 1/2 the stroke plus rod length plus comp distance and subtract that from your measured deck height, thats how you figure how much out or in the hole the pistons are. Adjust from there with deck surfacing/milling, head gasket thickness, head milling if open chambrred, etc

Thanks, comes out to the exact same distance as a stock 340. .018.
