340 Crankshaft bit the dust

H series were ~$88...King SI standards were $37, worth it to me to hit them with a dremel and clearance them myself. I thought about it until I saw the H series price.
Yep, between Main and rods... 180.00ish
If you make a clamp jig and/or have a decent belt/wheel sander....its easier to mod the bearings...but full groove main are where it's at.. depending on clearances. Just slot oil the feed holes on 1-4 main bearings..
