Mechanical fuel pump arm to timing chain clearance
Restarting 455 build project ...mechanical fuel pump arm is rubbing against double-row timing chain even though the arm on the fuel pump does have a curve in it .... is there a mechanical fuel pump that has more of a curve that will clear the timing chain don't want to go with an electric pump.
Thx in advance

I’m curious, what pump are you using?
I remember having this exact problem with the cheap Holley mechanical pump on a 425. I solved it by using a rat tail file to slot the mounting holes just enough to clear the chain. Crude, but effective.
