Theres a couple bearing issues we have had to deal with and find ways of overcoming. The first is when you use a crankshaft with large radius ground into them you can have an issue at the rear main bearing. That's caught us once a couple years ago early and a Dyno session. Basically you want to grind about .030 off the very end/rear section of the main bearing to make sure there's plenty of clearance for the large radius. The second modification is drilling a secondary oiling hall at about 8 o'clock position to deposit more oil. This also requires trenching out behind the main bearing to connect to the oil hole.
