How much oil pressure are you running? I have only run this engine for a few minutes (several short runs) in the garage before the hex drive broke. Since the oil was still cold, it made plenty of oil pressure. This pump and relief valve spring typically made 60-65 psi with warm oil and higher than idle type RPM. I didn't notice any oil pressure issues until it went to zero. I expect to start it again on Wednesday. The investigation is done, the new bronze gear oil pump drive shaft is installed, and I put a new oil pump in just in case. I primed it with a drill late today (Tuesday) and it all seems normal.

Good comeback from the freak failure.
I heard of one other brand new MP intermediate shaft snapping like that at a local race shop, close to 20 years ago. The builder scrapped it, put in a different brand and never had another issue. Thinking it has to be bad heat treat or similar, like the guys are saying. Just glad to see you caught it now!

OK, things went well this afternoon. - I primed the engine with a drill (again), before installing the oil pump drive and distributor. - The engine fired right up ! And oil pressure was 70 psi at 1700 rpm. - After running a few minutes in the garage, I turned it off and checked for anything unusual. Looked fine. - Started again and drove up and down the driveway 4 times to check the transmission in all gears, including reverse. This was the first drive with my PG since I put the 1.80 straight cut planetary gears in it (was stock 1.76). All good. - After letting it cool in the garage and doing more checks; I drove it up and down the driveway a couple more times for fun. Good day all around. Sunny, 60 degrees; and the car moves!

LOL, I am too much of a neat freak to put tire marks on my new concrete driveway. Unfortunately, no local tracks have a test and tune this week. Usually two tracks have Thurs evening T&T, but they are having special events all week. And Farmington typically has a Friday night test session with motorcycles, street cars, etc. But I don't know what the surface is like with mainly street cars and motorcycles. GALOT Motorsports Park - Spring Fling Big Dollar racing. I may be able to Test at Piedmont, if they allow it during their Tuesday or Thursday special events (May 3 or 5). I need to phone them. Farmington Dragway has a Mopar event Sat May 7.
