    Default Vintage Tow Rig .....

    .... Perfect for towing a vintage jet. Traded the BMW for it. Sad to see her go, but the motorhome will be more usable for us, and will be worth more in the long run. Just gotta get a few minor things worked out mechanically, then get a hitch installed. Front wheel drive, '70s motorhome ... groovy. Thank goodness it doesn't have one of those groovy interior color schemes!
    The '78 CV23 should look right at home behind a '78 motorhome!

    Sweet. Should be 454/TH400. If you found a lightly-wrecked late-model GM van with DuraMax/4L85E, it would make an excellent donor for transplant. That's a lot of weight for a 454 to move around.

    I've seen a few with a Duramax transplant, but it's big $$ to adapt it to the TH425 FWD transaxle. These are fairly light for their size (26'), around 10k lbs. She has the original Olds 403, rebuilt with ~40k miles. Trans was rebuilt at the same time. Original 3.07 diff was replaced with a 3.21 from a '66 Toro, so it'll do a little better towing. These have a COD of 0.31!

    Wow. I'da lost money on the .31!

    I didn't realize they were FWD. The THM425 is a stout TA, Turbo 400 parts as well. A 455 would work better, but.....

    +1. Unfortunately they opted a move to the 403 for the final two production years, '77-78. Earlier coaches got the 455. Damn '70s oil crisis!

    I have two complete 455 Olds motors - intake to pan. Let me know if you need one. They are just sitting. We would just have to make sure one was viable before I would sell/trade it.

    Yep. She was a beauty, and I had just about all the mechanical gremlins taken care of too. In a way I do miss it, especially when hitting a wide open, empty, long stretch of road. My '05 Saab 93 Aero w/Stage 2 tune is very quick and fairly agile, but there is just no comparison to that V12 torque and sound on an open highway.

    I learned a little about these because I have 71 Eldo and the FWD setup is the same.

    Check out this guy in California Applied GMC. He runs a 540 inch El Dorado motor in his. He's an older guy that likes to talk on the phone. He has a lot of good advice on these.

    and one thing I learned. If you need new axles don't buy new ones. Send this guy your originals and have him rebuild them. The originals are heavy duty. The new ones from China not so much.

    Something else I just remembered. Watch the front wheel bearings. Unless they changed the design by 1978 they are pressed into the steering knuckle and the hub is pressed into the bearing. You can't grease or service them unless you remove the knuckle and press the bearing out of the knuckle. The guy I mentioned above will actually drill and tap the knuckle to add a zerk fitting when he replaces bearings. Then you can grease them with a gun.

    Nice trade. Your setup will look cool with your boat too. I bet you'll spend less maintaining the RV than the Vintage Bimmer.
