My take on the oiling system crossover tube for the small block

I'll go with whatever krooser comes up with
We fed from the front and fed the rockers externally and did a bunch of other things that probably made little difference- like the cross over tube- but they did not hurt
the tappet leaks hurt and the rocker feed hurts
now we get all this working and YR comes up with timing
I guess when we slotted the main saddles and fed from the side we were somehow addressing timing as well as getting a better hydrodynamic wedge for the mains
listening
never done 8500 in a SBM never had the heads to feed that
