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

This is what I am running in my 1993 magnum with LA style Trick Flow heads. It's a Cloyes Street True Roller with 9 degreeing slots. According the Cloyes the difference between the LA and Magnum sets is that LA set is the camshaft sprocket is balanced to work with a fuel pump eccentric. See the picture below that might help. I am not using the eccentric, but put it in to get the correct spacing since my cam is a LA based long nose cam.

Ah ha!

So then it doesn't matter running running an la set in a mag with a eccentric in place but does matter without one in place .
