True, I was going off of "broken". I know when I say broken, it means broken and not "sick" LOL! Problem with it being in a motorhome is that the caddies do not like Hi RPM's. 65 K on an older 500 caddy in a motorhome is not anywhere near low mileage. But that doesn't condemn it either. Worth diagnosing for sure.

THE REST OF THE STORY...
I was going by what I was told by relitaves of the PO. Now that I have it home, it turns out the engine is the origional 455 Olds and the trans is from a Caddy. So far the engine seems to be in reasonably good condition.
Preliminary measurements indicate the front floor would require serious modification in order to install the 6BT. That and other "problem areas" have me reconsidering the diesel conversion. Besides, I'm getting a little old for these kinds of projects.

OH Yeah.. The method of engine removal from one of these things involves erecting two "A" frames, inside the coach, supporting an "I" beam running from the windshield down to the door. You can imagine the rest of the procedure.

I believe the Olds and Cad transmissions are identical. I also think you are better off with the Olds engine, much stronger bottom end, better heads, more after market parts available, etc. The engine, trans, differential package is like nothing else. The gear ratios are matched to the torque of the engine (somewhere north of 400 # ft at a relative high rpm). A small diesel will not produce the same amount of torque, and what torque it does provide will be at a lower rpm, so transmission ratios will be wrong. As far as bolting in, a 6.2 / 6.5 would probably fit pretty easily, but these weren't noted for their high torque output. The biggest drawback to the 455 is fuel consumption, but you can buy a lot of regular unleaded for the cost of a conversion. Just my opinion.

I was thinking the caddy motor sounded a little strande. The Olds make perfect sence. I have seen those in there before. The diesel conversion would be nice, maybe a 6.5, would be easier. I still think I would stick with what it has in it. FYI that is not exclusively a caddy trans axle. As you can see it was also in the olds toronado. The 455 is a decent engine. I had one in a boat I had a while back. The valve train just sucks. It is non adjustable, but the after market can fix that.

I agree with you both.
To make the decision even easier, It RUNS!
I removed the plugs, filled the cylinders with Marvel Mistery Oil and let it sit for a few days. Bypassed the fuel tanks with a hose directly to the fuel pump from a portable tank. Cleaned all of the electrical connections, changed points, condenser, coil & plugs and it seems to be running smooth. The power steering and alternator are working and the radiator isn't leaking...so far.
I had to remove all of the brakes in order to get it to move out of the spot it where it had been setting for 10 - 15 years (according to the relatives).
It was FREE.. what did I have to lose?
Many thanks for the thoughtful responses from all of you.

Sounds good. Plan on replacing the brake master and wheel cylinders and calipers; after that long in storage, enough moisture was absorbed in the brake fluid to rust the cylinders. Enjoy your find!

I am pretty sure you will have leaks pop up, once you start driving the old girl. I had a 1978 Itasca that only had 26,000 on it when I bought it. And bot did I pay for that several times over. It sat and was barely used, they hate that. It is better to use them, than to let them sit.

It took me three days to dig it out. I had to remove all six brakes just to make the wheels turn. Moisture distroyed two outer bearings, they were replaced. All six tires held air and the onboard air pump inflated the rear air bags. The frame has surface rust but it looks straight and has no rest holes.

I drove it yesterday (around a 1/4 mile circular drive). I'm impressed! It seems to be worthy of spending some time and $$. The interior and all of the appliances are in really nice condition as well as all of the cushions and upholstery. My wife said "retro is in". She doesn't care for the yellow floral design.

Now to get it up in the air.
