    74 472/TH400 into 65 Calais?

    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.
    Help/advice appreciated.
    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.

    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.

    Thanks Al,
    The 472 came out in 68 I believe.

    Anyone else?
    Feel free to offer any advice/insight.

    Possibly your car already has a TH400 (switch pitch). If so, you are better than
    half way home. Check for the vacuum mod on the right, or the P-R-N-D-2-1 pattern.

    Bruce,
    My car (74 Fleetwood) has the shift pattern as you describe.
    You figure the 74 472/TH400 should drop into the 65 Calais chassis?

    Thanks,
    Glen

    He knows the 74 has a th400 , he was asking if the 65 had that shift pattern...

    Re: 74 472/TH400 into 65 Calais?

    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
