stock or hv oil pump

I just spent a couple of hours grinding on my 360 block (408) build I’m working on. Probably another hour to go then I will drill a few holes in the intake valley and champher them to aid oil drain-back. I see some 50 degree weather early next week so hopefully I can give the block a good bath. Dirty dirty work.

Notching the bores for rod/bolt clearance for 4" crank is always fun. Do the link bar clearance in the valley as well is always a good idea if a solid roller goes in.

Ever have the one rear lifter boss crack and break off?
