No engine. $100. If that's all you want, why not just give it away? On Facebook Marketplace. The ad says it's a '73, but trust me, it's a '77. https://www.facebook.com/marketplace/item/5360980677289965/?hoisted=false&ref=search&referral_code=null&referral_story_type=post&tracking=browse_serp:b47ab076-144c-4f85-89d2-f6f4d62d7928 It does have some useful parts, including both bumpers and grille, the often-deteriorated rear fender extensions, and passenger side remote mirror. It is also well-equipped with cruise control, twilight sentinel headlights (I don't see that option very often), Tempmatic A/C, trip odometer and fuel economy gauge, and AM/FM/8-track.
I wonder if this guy is so far out in the sticks that if he wanted to junk a car, he'd have to pay a towing service to come out there to retrieve it? For us New Mexico residents, think about how it would be a p.i.t.a. to get rid or a car if you lived out in Quemado or Reserve, NM - miles from any town of substance. I got a question for you Jaunty - if you were to take a 455 out of one of these - can you use it in a RWD car like a 70's big 98 without much adaptation?
First of all, the last year for the 455 was 1976. The '77 and '78 Toros had the new 403 V8 as their standard and only engine. But to answer your question, I don't think there's much of an issue in taking the 455 or 403 out of any Toronado and putting it in another car that had a standard rear-drive setup. The Toros had a transmission that was bascially cut in half and folded around on itself to put the power to the front wheels. There is a chain-drive mechanism involved. But all of the Toro weirdness is behind the engine, not on the engine itself, as far as I know.
As far as the seller being out in the sticks, it doesn't appear that way. If you look at what's in the background of the photos, it looks like a wrecking yard as there are vehicles scattered all over the place. In one of the photos, there is a large, concrete-block building in the background. If anything, I'd guess that the seller IS a towing/wrecking service.
I would say yes, I once pulled a 500 ci Caddy engine from a 76 Eldorado and put it in a 70s Seville that had a 472 and it fit and ran good. I think even the oil pan was the same or close enough.
Good news everyone! GM's traditional v8 family all used the same bellhousings for their FWD transmissions as their RWD transmissions, no special block castings for them (unlike Ford...). If you get a FWD car's engine, you can put it in a RWD car without much trouble.
