The crankshaft will be offset ground, and Nelson explains why. "I bought a new 'blem' crank from Eagle that had been turned .010/.010 on the rod and main bearing surfaces already, and then I offset ground the journals from the Mopar factory dimension (2.375-inch) to a big-block Chevy size (2.2-inch). This will result in a 3.905-inch stroke."For readers with intentions of custom machining their cranks, or for those looking to save a few bucks on a new crank, the "blem" angle is a hot tip.
