Crank is a winberg, crack is small, crank too good to toss
What steel rod would you suggest?
Thanks for your help
Was the crack found after magnaflux or human eye..also can it be fixed ?
Yes rotating weight will effect any crack..hard to say from my end how much..I probably wouldn't try to compensate for the crack with a lighter rod that will need to be replaced often. You are not guaranteed the aluminum rod will add any extra life to the crank...but to answer your question on steel rod. PAR uses manley 4340 on some of his 1000 hp stuff I have used Callies same 1000 HP engines...
