    Is there anything i need to do to the new oil pump to help it with priming for the first time before i bolt the oil pan on? I just ordered a oil pump priming shaft from Mancini racing.

    Should be no issues since you will prime the pump manually.

      Course you'll know to slowly turn the motor while your assistant runs drill with the priming rod. If your assistant holds a slow steady speed they will feel the lack of resistance when you get the cam lined up with one of the heads. At that point stop and see what side is getting the oil coming out of the rocker shaft. Then slowly turn the motor till it happens on the other side and you're good...
      My wife has been my assistant for this (very non car person) every time and now she's done it so many times that she shouts out there it is there it is! Lol...

      This must be a very old post because you always say you're in your early thirties...

      Since IIRC the OP is just installing a new pump on an already running engine, and the engine was running before, the process of checking the rocker oiling is really not necessary.

        I was smart enough to graduate HS at 10. My math may be off a bit though.

        I'll have to do that to each your own on this one.. if it was me I would definitely prime it and get the new pump full and the oil filter all full and everything like that. I'm assuming they're changing the oil filter... And the oil LOL..

          No one is telling him to not prime the pump or fill the filter, etc. Just don't put in the time to check the rocker oiling IMHO if it is an already running engine.

            This is why i ask... in all my over the parts counter conversations no one has ever mentioned to me to rotate the motor while running the drill. I thought you just hit it with the drill until you build pressure on the mechanical gauge? This is why i need that shop manual That Yellow Rose quoted. Thanks again for filling in the blanks guys.

              OK that makes sense now i probably have confused people on this one. Sorry for that i jump in and out so much because of my work schedule. I hate starting and stopping on a project like this especially when its something i really want to do. Unfortunately that's my life right now.

                Parts counter guys generally see Chevy and Ford. That's why when you go to the parts store all the spare hot rod parts if they have any are all Chevy and Ford.
                Although like mentioned you probably don't have to oil the rocker arms but it's a good practice and if you're there doing it I'm just having this really rotate the motor one time and kind of let it stop for a second where the drill speeds up a little bit I'm kind of watch the oil come out of whatever side it's hooking up with again is just good practice. It's seriously isn't going to cut into any more than a couple more minutes of your time...
                Very easy to do with the spark plugs out...

                  It's not only a Mopar thing, as this advice would apply to almost any engine. But I can assure you that millions of new/rebuilt engines have been started without pre-oiling, and certainly without the added step of turning the crank while pre-oiling. I'm going to say that almost nobody does this. But every little thing you can do to avoid a premature failure is a good thing!

                    I think everything you are describing here is a best practice. After all without oil you wont make it out of the driveway.

                      trust me I'm no one to follow the Sheep that's for sure. When everybody warned me about taking out the inner Springs before I broke my cam in I brushed them off and was no problem. But when it comes to oil through the whole system that's where I'm going to take the extra 5 minutes...

                      I'm puzzled as to why this engine was once painted black? Was that a Mopar color at one time?

                      That's just well-preserved cast iron. Rusty, covered with a little oil that has probably been there almost forever. Probably why the paint didn't stay on it.

                      I did have what looked like black paint flake off one of the heads. Maybe it is just cast iron.

                      A lot of the '80s-'90s engines were painted black. But I don't think that's what you have unless someone swapped heads at some point (would not make much sense though).
