    New engine acquired for HO conversion of the wagon

    So, in my belief that putting an engine together outside the car would be easier than swapping the cam and heads with the engine still in, I got a spare.
    I am doing this outside the car to afford myself time as well, I want to have the engine in the car in a few weeks rather than having to do all the work in a day with it in the car.

    I have an engine from a Mark VII(came with the PCM too, now I have 2), does it matter what year it came from?
    I read the thread about the timing covers being the same for most of these 302s and just wanted to make sure I am going this right, this is the first time doing any engine work.
    So far I have:
    - long block
    - GT40P heads
    - Explorer intake
    - Mustang shorties
    - 19# injectors
    - new water pump(Ford)
    - new oil pump
    - new oil pan is coming(the one on the engine has a hole for the oil level sensor, I just don't want a big hole in there and I don't have that sensor currently)
    - all gaskets needed(I think, it came as a full kit so I hope it is complete
    - Mark VII PCM to keep cruise as stated int he HO thread
    - I also have a Mustang cam if it matters which one I use


    Is there anything else I would need?

    Any help would be appreciated.

    Some Mark VII's had lopo's in them, what year is your out of?

    For the gt40p's, you'll need aftermarket valve springs, though it wouldn't be a bad idea to have the heads gone through by a shop. Bear minimum I'd clean them up and lap the valves.
    Wouldn't be a bad idea to throw some 1.7 roller rockers in either.

    I'm assuming your using a Explorer Throttle Body? You'll need a lighting EGR spacer, or to modify an aftermarket Mustang 65mm.

    If it's an HO, cam is the same as a HO Mustang, so no need to change it. I'd replace the timing chain though while in there.

    I'd get new o-rings and pintle caps for the injectors. RJM tech used to sell a nice rebuild kit but as far as I can tell is dead.

    What do you plan on doing for the rest of the exhaust?

    For the trans you'll need the proper governor, or else it will shift at ~4k, way to early for a HO cam. You may as well get a better convertor and at minimum a shift kit too.

      I forgot to list the 1.7 rockers and aftermarket springs but I have those too.
      I have a Mustang TB that I'm modifying to work.
      Ok, I just re-read the HO thread about the Mark VII cams 89-92. I believe this is an 88 so that answers that question, is there a way to tell for sure what year it was? PCM code, some identifying marks?

      I have a Mustang H-pipe and some over axle pipes(Impala) for exhaust, still deciding on mufflers

        If it's a D9S it's HO. I think a few other codes are HO as well.

        I probably run an Explorer TB, 65mm vs a Mustang 60mm.

          Alright, it came with a DX3, I do have a D9S from a '91 that I bought for the swap a few months ago though.
          Ok, the governor is ordered.
          The TB I have is 65mm, it came with an HO intake, the cam, and some other stuff I got a month or 2 ago.

          I just found another thread here mentioning the DX3 being used in an HO conversion.
          I also saw elsewhere that the upper plenum being stamped HO means that it was in fact HO, correct? (the one this engine came with has HO cast in the top under the plaque)

            The non-HO and undesirable HO motors use a goofy looking spark plug, same one the non-HO uses. Pull the plug out and look at it. If its got a long neck above the threads, its got crappy heads, or isn't an HO. If its got threads right below the hex nut, its the desirable motor. The Bill Blass from 86-87 had a lopo, the LSC had an HO with flat top pistons and crappy heads. All 88+ have the HO with better heads and valve relieved pistons. Heads don't matter if you are changing stuff, its more the pistons that are a concern. If its got HO cast into the upper intake though, chances are extremely good its an 88+ motor and you're good.

              It was listed as an 88, I'll take the heads off tomorrow.

                Where did you order the governor from? There is at one time, may still be a good write up about changing it out on this forum.

                  I ordered it from Ford, to be picked up at the local dealer.
                  Yeah, the write-up on here is where I found the part number.

                    Then it certainly sounds like you have a HO, which is a better starting point IMO. Although the only main difference short block wise is the pistons, you get the nice forged flat top's, instead of the shitty lopo dished cast aluminum ones.
