Also, why whittle that long, twisty crankshaft all the way down to SBC bearing diameter? Are there no other main bearings available which are closer in size to what the stovebolt came with? I've really enjoyed watching how people are using pistons from various other engines, maybe something like an Isuzu diesel would be closer in diameter? Also maybe wider, aren't SBC mains thinner versus the stovebolt?
