The Comp AMC lifters oil through the stock Mopar oiling system through the sides from the stock lifter bores, does your block have provisions to oil the lifter bores? scope
Mine does with a .060 size hole to the lifer bores shruggy I'm planning on using that system to oil my rocker arms with pushrod oiling luck
