52 Fleetwood - What powertrain bolts right in?

[Tom Kieffer]

I have a 52 sedan 60s and want to get it on the road. It needs a complete engine/transmission transplant and I want to know what all years will bolt right in as a complete unit.

1. Will any 49-52 331cid bolt in?
2. Any later powertrains such as 365 or 390 as a complete unit? Forget the 6volt-12volt issues.

Any donor cars for sale in the Pacific Northwest?

and yes I will be at the Portland Swap Meet next weekend. Ill be the guy with the cardboard sign around his neck "Caddy Parts Wanted".
