I have some definitive disagreements with some of what’s been posted and or alluded to hear in this string.
1) a Billet has a long way to go before it’s as strong and as durable as a non twisted forging, since a billet does not have grain running the optimal way through out its make up .
2) besides the crank being far less likely to crack when a nice radius is ground from a journal to the cheek, the proper phasing of the weights on the crank can reduce loads by thousands of pounds which is critical to the life of 2 and 4 main .
