I see what your trying to explain. So if someone would plug the hole from the mains and just leave it open for the rods this would be exactly what the LA crank would have.
I wonder if this would work?
I plan on testing this theory in the fall with a junkyard 5.7. If my friend is willing to help me.

the results would be positive
