Ive seen factory cranks that werent drilled all the way through or perfectly centered. What was left though was paper thin pretty much.

I just ripped it out and finished it with a dremmel. As I didnt want that stuff ripping itself of and Finding its way to the oil system, as Bob eluded to.

Now on the steep angle/ dont recall Dont know if that would be a problem or not.


Of the Two 440 Source kits I had one was Bad and one wazs Good just kidding thats for 540
