Hi, this is my first post and I'm hoping to have a lot more. I have a 1966 jeep CJ5 with the 225 buick V6. It's not running and at a future date I want to go throu it and rebuild it so my classic is still a classic. In the mean time I want to get another buick v6 Used or a rebuilt and drop it in there. I know buick made a few late model cars that had RWD that I could swap out. But what are they? It's almost impossible for me to find a decent 66 to 77 V6, but maybe I would have more luck finding a later model. Any advice would be a big help. Thanks

 

I'm pretty sure GM made RWD cars up to 84. After that there may be some exceptions.

 

What Hanky said. The only RWD Buick made into the 90s was the Roadmaster, and that only came with the v8
