I havent had a cadillac with a cadillac engine for a couple years as i usually just discard the body and stick the engine and tranny in the extra pile but this coupe is pretty nice for an Ohio car.
did you ever get that 500 inch project up and running ?

I'm not in much of a hurry, with winter setting in. My plans are to have it on the road by mid spring. That gives me plenty of time to get the mechanical stuff in order. The body will wait until the following winter.
What year is the coupe?
I'd like to find a 70's Deville but finding one in this area, without swiss cheese sheetmetal, is kinda hard to do.

Bolts right in. I have an '81 with a 500. The '80-'84's are the same. When I installed the Olds 350 in my '84 Coupe I first used the TH200/4R. I will installing a 500 in this car also to replace the 350. When the 200/4R went, I just replaced it with a rebuilt TH400. The crossmember accepted the TH400 with no problem. The car frame has two sets of holes for the crossmember. I also used the factory driveshaft. The TH400 is only 11/16" longer (with the short tailhousing) than the TH200/R4. To use a TH400 (instead of a TH375), you need to get the larger TH400 32 spline yoke. You also need '80-'84 RWD 368 motor mounts. I am not sure if they are the same as the ones on your 500. It might be a good idea to replace them anyway because of age. The 4100 frame mounts work. The only clearance problem (which won't affect you) is the passenger exhaust manifold on the 472/500 at the front. To use the 472/500 manifold, you have to "clearance" the front of the upper A-arm.
While I have not installed a 500 in my '84 yet, I have installed a 368 to replace a 4100 in my '82 Coupe. The engine came out of an '80 Coupe. The 500 is in the same 368/425/472/500 family.
You're in for one fun ride in an early 80's RWD Caddy powered by a 500.
