I think the simple fact, Mark would have looked over this crank if I sent it to him to use it. If it would needed this much Mallory, he would have offered me a core N crank to use instead. If I do anything with the 403, especially for a truck, it will be external balance at a different shop. The 11 months was more of a piss off. I assumed it would take less time and money to do it local vs sending parts or paying core charges to Mark in Florida. Apparently not, it just adds to another wonderful year.
