blykins, when talking to the guys at Joe Gibbs on oil recommendations they thought maybe the larger journals could be used depending on the 351W block ordered. My block wasn't cheap by any stretch PN 31345235. DART says in their description "Two main bearing diameters of 2.249 in. or 2.749 in. allow choice of small or large journal crankshaft." I've checked the BOM and can't find anything that gives away what configuration I have - what part/part number would give me that info? - yes, I'm a rookie at this stuff.

Dave, the motor has been run in and no heat issues - actually runs on the cool side at 175F in the engine stand.
