Hi All,
As many of you know the early, small journal, sbc cranks did not have a balancer bolt. They relied on an interference fit to retain the balancer. I have never been comfortable with this and even Chevy started putting in the balancer bolt in the late 60's. My question is, has anyone ever drilled the end of the crank and threaded the hole for a balancer bolt? I know I could take the crank out and drill it on the lathe but that is a lot of work. If it has been done by hand, and works, that would be my choice of ways to do it. Has anyone done it this way?
Rick
