Magnum timing chain with LA timing cover, and fuel pump eccentric

No worries brother. I’m going to have the machine shop Mic the crank for the magnum and we will compare findings.
I should have taken my cheaters out with me and I could have mic'd them.

Well FWIW, Summit lists several timing sets for the Magnum separately from the LA, so SOMETHING is different.

I wonder if it has anything to do with the tensioners on the magnums?
