Guys, I have a question. I dropped of my factory forged crank at a machine shop for a once over (crack test etc) to see if it was worth using, it came back with it being machined 030 on the mains and 020 on the rod journals. When I told an engine builder whom is helping me build it, he lives 2 states away, he said it shouldn’t have been machined as it was done without the engine block. I am waiting on main caps from Canada. He is blowing up hard saying it shouldn’t have been done.
So my question is: the crank is machined, nothing I can do about it, what’s done is done. Obviously when I get the main caps, I will get a line hone, can I still proceed with my build? He is carrying on like it is the end of the world and its not worth doing because I don’t know what my clearances are right now. Where do I go? I can’t really see a reason why I can’t proceed, the machine shop has already found a set of bearings to suit the new machining job of the crank, and found the bearings easily, a set of Clevite bearings.
Thanks in advance.
