    I beg to differ.

    mid 70 full size LTD, T Bird and Cougar have 351M from factory and they do share same bell housing with Windsor family.

    The big question is.....

    Which 351M does BlackJack have?

    351M/400 DO NOT have the windsor trans bolt pattern, they have the 'big block' bolt pattern.

    Those 70's cars I believe used the FMX with the m's didnt they?

    All 400's and 351m's had BB bolt patterns. They came with C4's and FMX's and some trucks had sticks. The c6 from his windsor won't bolt up.

    I do know the '76 Ranchero GT that i used to have had a 460 and a C6 in it...would do a one-wheel-peel as long as you kept your right foot planted, too

    And...as mentioned a time or two in this thread already,
    351M/400 ARE THE SAME BOLT PATTERN as the 385 series "big blocks" (429-460)
    In fact, distributors will interchange as well...
    Trust me, they are the same! I've swapped a 460 into a 351M truck.

    Was a post on FTE sometime back...i think the gist of it was that the FMX was a car only transmission..and I think by 1978 that big ole Tbird most likely woulda had a C6 anyway...
    i could be wrong on the trannies tho..

    There were a few early '71 400's that had the small block pattern, but they are few and far between... All 351M have the BB pattern...

    My Pop had a '79 Cougar 351W and it still had the FMX tranny... Wifes aunt also had a '79 with a 351M that had the FMX. My guess is they went with that tranny because of the removable bell...

    Yep, I think I need to do more reading on the transmissions...I will admit that's one area I'm not as knowlegdable on..
