My 422 smallblock build

828-2 is the one that’s been around for years. No mods to the oiling system usually not needed with this lifter, unless the lifter bores are worn.
Still have to check it, as one lifter puked oil at max lift, and I was able to move it to another cylinder and it was fine.
70-80 pounds of oil pressure, and no losses.
A ton of grinding in the lifter valley for clearance on the guide bars.
I should check them in my x block, as I’m not looking forward to a dozen hours of hand grinding.
