Not sure if its the Eagle crank having larger weights, or my block being thicker down there, but just checked the clearance to the machined releif area, only 0.005 to .015 clearance from web to web.
By reading some other posts and forums, people usually just drop it and start torquing things down.
I've never used an Eagle crank so I don't know what sort of issues they have. Molnar cranks typically drop in and clear just fine as do SCAT fully machined cranks. I've had clearance problems in the past using Mopar cranks. Typically a 4.250 crank is going to have a low bobweight so the counterweights need to turned down anyway.
