Just wondering if this would be a straight "drop in"?
I have a 74 Fleetwood with rotted frame and there is a 65 Calais for sale locally; good body/frame but needs drive train and rad.
The 65 is headed to the crusher if not sold after next weekend.
Has anyone done this swap?
It appears the Calais didnt get the 472 until 68 and the 65 had the 429.

Re: 74 472/TH400 into 65 Calais?
I wouldn't think it would be too hard. You would think it would be a drop in since the 67 and 68 are practically the same car and one had the 429 and the 68 had a 472. You would think the frame mounts would be the same but I don't recall seeing hardly any 472's in those early 60's Caddys. somebody should come along with a definite answer. I hope they hurry up because I always hate to see classic Caddys getting crushed.
If the 65 already has a TH400, its far simpler than conversion from a Hydramatic. However, a
65 doesn't bolt to a 472, and the 74 TH400 may have a different tail section length. Taking the
2 TH400s apart will allow assembly of one that fits the 65 body & the 74 engine. If original, its
way overdue for a new $28 seal kit, even if working fine. I'd recommend keeping the 65 switch
pitch function. Bruce Roe
