2 things.. whats the weight oil and what is the minimum rpm you see 80#  I run 10w30 Lucas synthetic.. and to be honest most of the racing I do is 1/8 Mile at night.. and it's very hard to get a bead on the gauges... from a few videos that I have watched... at speed the Gage is always around 80.... typically idles 1500rpm at 55lb hot

Shiloh, maybe when the pan got crushed it may have fractured the pump & it finally broke off. hey Rick good to see you around... and yes this has kind of been our thought to.... mr. P are you suspecting pressure

The passage is way off center too. One more thing to check. I'll be looking at all of mine this weekend.
It may be ugly, but it sure is slow.

How big is the outlet hole opened up to? I allways open them to 1/2" and never had this happen. I have had pick-up tube break off and fall in the pan, but never the pump. I see yours has the pick-up in cover, just like the set-up in my Demon. mine was just a tick larger at 17/32...this oil pump has had a ruff ride..may the next one will have a belt..

Sorry to see this after all of the other bs you went through man and hopefully it's repairable...........that thing flies and you should be proud of your efforts and results so far......  the crank was fine I will ship the rods to Oliver... I think I can buy two and have them put new bushings and new bolts in the others.. I think I'm going to step up on compression... this motor was originally built for bracket racing. and e85 but I never expected it to run this fast.. now I'm caught up in the heads Up Racing stuff..so time will tell..

Glad to hear it appears to be not so bad...No better time to step up the game than now.

This weekend did not end up so good.. although I guess we could say it could have been worse.. the Car slow down almost for tenths on its last pass.. after picking up my losing time slip.. re fired the motor and noticed it didn't have any oil pressure.. and the starter really struggled to start it... I got it home.. remove the oil pump and found the oil pump Lane in the oil pan Is that a crack on the left where the oil pump cover bolt goes in? Matt
