455 block with stock 455 crankshaft. I see it now, that's the counterweight passing under the cam every revolution. What if the counterweight is kissing the pump shaft or the bottom of the dizzy gear? Would that leave any witness marks? Since the driveshaft turns 1/2 as fast as the crank, the shaft should show two marks, maybe one worse than the other.
That is one thing I was worried about on my 434 stroker build. I'll post some pics I took of my build, to show how close those parts are. I took some good pics of the area when I mocked everything up.
