Hi everyone! I was wondering if I can get some opinions on the best way to install the lifters on a 440. I am to the point of my rebuild where I am installing the lifters, pushrods and rocker assemblies. This is a mostly stock engine with the only modifications being slightly larger valves, a step above stock camshaft, etc. It is a hydraulic flat tappet camshaft. In the past, I have primed hydraulic lifters by placing them in a pan of oil and used a drill press with part of an old pushrod and pumped them up and down some while immersed in oil. The machinist I used for this build is telling me he prefers to assemble everything without priming the lifters and letting them get primed by priming the oil system with a priming tool on a drill, spinning the oil pump. I planned on doing that anyway but I wonder if that is sufficient to prime the lifters if I install them without pre-priming them. Thanks for any help or suggestions.
