OK, thought u guys might find this interesting. I posted yesterday about the curious shallow circle scratched on inside of my 360 timing case. I immediately knew it had something to do with fuel pump eccentric. But it was too late. I was tired This morning i figured it out. In short, whoever put the motor together was an idiot. You could stand over motor and look down and see that the forward edge of eccentric was not parallel to front of block, but slightly askew. That gave just enough extra reach for it to reach forward and hit inside of case.
I couldn't figure it out until I took off the eccentric to find they had not seated the slot in the eccentric down over key in cam!!. They just bolted it down any old place.!! They tightened that bolt down so tight it distorted the little cup-like washer the bolt goes through. just smooshed it down. And in tightening it like this they smooshed out the key too. When i went to remove cam gear it wouldn't come. I tried harder with a bar, and the cam gear just snapped This is when i realized the key was smashed out and preventing the gear from sliding off cam . So I took a punch and hammer and attempted to re-shape the key, which worked, the broken hub then came off.
How somebody could not notice a key and a slot is beyond me.
