"a 4340 non-twist forging" -wow, non-twist, somebody likes this project.

Since crank fractures happen at the journal radiussess BEFORE ever happening at the oil-drillholes, I ask aboout Radiusing: Traditional old PMD radius cut, or the new-ffangled undercut technique?

Also, what is the optimized Main Bearing set for the new crank: upper half-groove, 3/4groove, full-groove?, no groove=grooved crank, funky groovey. HIS
