The Block and Bottom End:
The Eccentric Problem

No project would be complete without a small amount of modification. We've already seen some mods done to this engine, but the next hurdle was a bit perplexing. The problem lie in the fuel pump eccentric; that part mounted to the cam gear that drives the mechanical fuel pump. Let me explain:

This is how a stock cam gear for a 351C usually looks. (this one has had some filing done to be a "special too for another project, but you get the idea). In the center of the face, there is a ledge. The dark area is actually raised about .050 above the rest of the gear face. This is to accomodate the two piece eccentric that drives the fuel pump.
Here, the first of the two pieces is fit against the old gear. Note how the inner edge clears the entire ledge on the gear. The next piece that goes in has a tab on the backside that will fit into the cam pin alignment hole.
And now, we place the second of the two pieces. This one fits against the ledge and the bolt holds it firmly. The outer ring is allowed to turn freely, thereby reducing any wear on the eccentric or the fuel pump lever. The light area in the eccentric is where the bolt washer sits. So that's how the two piece eccentric fits. Unfortunately, with the flat face of the Pete Jackson drive, I can't mount this same setup.
