    Re: 1984 Coupe DeVille Engine Swap!

    I once helped a friend pull the engine and trans on a '75 Electra. The driveshaft didn't want to budge there, either. Finally took a rubber mallet to it. A few light taps and it disengaged nicely from the trans and rear dif. Don't know if it's on point, but that's my engine-pulling experience right there.

    Wedge a bar or a big screwdriver in between the u joint and the yoke and pry so it forces the shaft into the trans. A couple of smacks from a rubber mallet will help, too.

    Thanks for the tips guys! I've got a nice assortment of pry bars in the basement, and I'll give that a try along with the rubber mallet. Tomorrow is gonna rock...

    Re: 1984 Coupe DeVille Engine Swap!

    So, I have some updates.

    We started the day off by taking out the driveshaft. The introduction of a pry bar to the situation worked perfectly. Thanks for the tip!


    Then we undid the trans mount (2 bolts) and the engine mounts. Instead of unbolting the six engine mount bolts, we just took out the 2 through bolts. This worked just as good. Weirdly, all the bolts came out like they had been coated with anti-seize. They came out so easy! (Sorry the pic is kind of blurry, it's the trans mount under the car.)


    I do have one important thing to say. If you are planning on removing one of these HTs and are going to replace it with something else, chances are you aren't going to re-use the exhaust. My advice is to cut out the crossover pipe. It hits on the frame crossmember otherwise, and makes it a pain to get the engine out. We ended up sawzalling mine.


    Up comes the engine and trans...


    Hmm. Seems as though something is missing.


    The massive hole where the engine used to reside. I'm going to powerwash this out on Monday or Tuesday. Might even fog it down with some fresh black paint.


    Ahh. After a few hours work the engine and car side by side. Front end sits a little higher now.


    Great. Now I have to clean all this mess up. Who wants to help?


    The new engine and cleaned trans might be scheduled to drop in next weekend. I'll post more as I swap the accessories to my new engine. Thanks for all the help and encouragement guys!

    You could have just left the compressor hooked up and moved it to the side so you didn't have to let the freon out...

    If you need a little more space when you are swinging the engine in, just let the air out of the tires

    I'm going to try and frankenstein the HUGE A6 AC compressor into the system. (that compressor is from the '76 Cutlass the engine came from) My auto instructor has access to R12 at the college, and he is teaching an AC class this summer. Soooo I'm going to have a SUPER-COOLING AC system this summer if I can work all the bugs out of it. So, if I post pics of snow in my car, you'll know what happened.

    Looking good. Are you gonna put the rear sway bar on from the 91?

    ^Front and rear from the Tow Package '90. It'll be a while until that happens though. I want to get the engine sorted first.

    Put the bigger rear end in from the 90, as well.

    Re: 1984 Coupe DeVille Engine Swap!

    Well, I'll help clean the mess up if it's still there next time I visit Michigan...Never been there, but it has snow and trees, so it must be alright.

    That is a field I am VERY experienced in actually. A Coworker asked about my car's name and how I knew to give her a Girl's name. I told him I knew She was a Lady, because about once every month she starts acting all bitchy at me and leaks out quantum amounts of fluids. If I had all the money I've invested into fixing her up, I'd be posting photos of my engine swap too.

    One day...one day...

    Re: 1984 Coupe DeVille Engine Swap!

    Jay, I'd love to swap in the rear from the Brougham, but it is non-posi, drum brakes, and I don't want to lose my 3.42 gears. I'll upgrade the rear when I find a posi/disk rear. My 7.5 rear end should hold up well enough if I don't beat it too badly.

    looks like a very clean body on your auto from the pics.Nice model . I looked but may have missed it,; any upgrades on the motor ?? You say you are in Florida but sig says Michigan ? My guess is Florida with the car so rust free.

    Anyway, looks great.Oozes potential.
