Gen 5 crankshaft This has probably been asked a few times. Will a Gen 5 crankshaft (LT1) 6.2, 8 bolt flange crankshaft work in a gen4 6.2? Bearing sizes, snout length and diameter etc. the same or doable?

ItI called Callies sales dept. and asked them because there's already an online article using one of their 4.00 stroke cranks in a GenV . It's the snout of a GenV crank that is the main difference, its not stepped like other LS cranks, it's all one dimension, the dimension is the same as the largest thickness of all other LS cranks where the crank gear rides. So,it is my understanding that if someone were to use a GenV crank in an earlier block or other application they'd have to turn down the outer portion of the snout to earlier LS dimensions or ream/machine out the balancer. The GenV cranks are supposed to be forged, have an 8 bolt flywheel pattern and are turning up on ebay and alike for not much money, an option for anyone wanting an upgrade over a cast crank.
