Problem with my Ford 302

Thank a lot for your advice. I'll do it that way.

And don't reuse that oil pump,the price of a new one is cheap insurance.

I think your problem lies somewhere in the clearances of the main/rod bearings, I'd double check the crank journals and clearances with the rebuild.........
Sounds like you spun a rod bearing,5200 rpms is not very high and should not have caused this, stock 5.0 Mustang GT motors had a 6200 rpm limiter in them from the factory!!!!!!!!!!!!..........definetly go with a new oil pump with the rebuild.....

I serouisly doubt your oil lost it's viscosity and caused this.....I normally run oil temps of 230 to 250 degrees in my 331 cu in race motor for 20 minute races, running usually from 3500 to 7000 rpms, motor has been in the car for a little over a year now and has at least 18 races/track days on it.........
The last race a few weeks ago, I was running a lot harder than normal and staying in 3rd gear more than normal and ran it up to 7000 rpms at least three times each of the 12 laps we ran, my oil temp went to 260 degrees and stayed there the whole race, oil pressure was about 45 psi, after a cool down lap things came back to normal............
