Kam, Just a thought. If you haven't already done this,you might check the OAL of the intermediate shaft as some of the Milodon set-ups use a longer than stock shaft. You said your older set-up was a Milodon. I don't know what length the Muscle Motors unit uses. Our KB cast and billet pumps all use the stock length shafts. If you use the longer shaft with our pumps it bottoms out and will not seat on the distributor bushing. From the photos it looks like there was a lot of pressure forcing the rotors into the cover and the bronze gear....not fully engaged on the cam because the shaft was not seated on the bushing? Then again I could be totally off the mark but thought I would throw it in as something to look at.




I think Ken might be right with the length of the
intermediate shaft... it doesnt look like the bronze
gear was wearing in the center where it would normally
wear and it doesnt look like the top of the gear has
the same wear like its setting up high

Also the bottom of the bronze gear was worn from the bushing in the block. It was a fair amount of wear!

I will try to get a pic

I pulled a rod cap. What do you think?

I hope I'm not stating the obvious but it looks like the bearing is hitting the chamfer on the crankshaft Did you make sure you put to put the upper shell in the rod and lower in the cap.


best so far 8.53 @ 158.59 MPH 60'1.240

Rob (KamKuda) did not assemble the motor ; Blame that boo boo on Mopar Performance.

The motor was purchased used and came out of a street car.

with the chamfer comments....surprised to see this in an MP crate shortblock
