Really, what's the big picture? I'm using a stock cast iron crankshaft for this build. I'm trying to reduce rotating weight. Trying to balance cost vs weight reduction. The original question was if there was any weight savings going to the Chevy size pin, there is but not a lot. Connecting rod is a little lighter. It all adds up. Never said I wouldn't use the Chevy pin size. Just wanted to see if there was actually any weight savings.
