Bad Day, Very Bad day

Tom, I don't think the shaft is broken. It looks twisted to me. Hard to tell from the picture though. I bet something has gotten into the oil pump and locked that pup down. Can you get a better shot of the end of the shaft? I wouldn't use an HV pump in anything that was under 7K RPM and also not without a hardened oil pump drive shaft. Those HV pumps can really have a lot of drag. I guess it's possible that the stock shaft got weak and gave it up, but most of the time that happens, the oil pump is locked up. It does not take much. A grain of sand can do it. Give me a shout if I can help you. You've got my number.
