I can only go on factory specs and advice from those in the know, and that's what I have been told. I advise my customers to use the rod listed for their Gen of motor to alleviate any possibility of problems. If people want to fit old rods to new cranks and new rods to old cranks, then go for it. But don't come to me with a broken motor crying foul and expecting a replacement
The advice given is done so in good faith. You can take it or leave it
