Slick 60's

Ok so I'm prett sure that a c6 off of a 351 Clevland will fit a 351 Windsor but will a 351 modified tranny fit a 351 Windsor?? I'm assuming that it will because the Clevland and the modified are both in the same engine family but I dont want to buy and parts unit I get someone else's opinion

Thanks

in a word no, the m has 429/460 bolt pattern...

There were a very few 400s made with the smallblock bolt pattern but they are very rare..The majority of them had the big block 429/460 bolt pattern..

Nope, different series

221V8/260V8/EARLY 289V8 (All are 5 bolt bell)

Later 289V8/302V8/351W V8+302Boss & 351C all same bolt pattern (6 bolt bell))

351M/400M/429 Lima/460 all same bolt pattern

FE's have their own bolt pattern, 331/352/360/390/406/427/428
I may have missed a few displacements(or be out on size), as there are some odd industrial sizes

as for all the various inline 6 cyllinders, I have NO IDEA....but sure would like someone to straighten me out on that front, as a conversation shortly after I bought that '64 M350 with a local fellow who is both journeyman mechanic & partsman listing all the sizes A& families of I-6's had my head spinning!!

Well that's why I asked because this website is a wealth of info

Thanks

Hard to believe, but true.
A few very early 400's had the small block bell housing bolt pattern. I found a couple years ago on '71-'73 full size Ford wagons. Never found any in cars.
I wouldn't plan a build around a 400 with a small block pattern, but I do know they exist.

The 385 series engine family is 370/429/460 and sometimes called Lima engines but officially the Lima engines are 383, 410 and 430's which were the engines the plant was designed to build originally. The 335 series 351M and 400 have the same bolt pattern as the 385 series engines.

Also keep in mind that there is no such thing as a 400M, it is 351M/400 engine family. The 351 has the M because they needed to differentiate between a 351C, 351W and 351M but there is only one 400 although some blocks did have dual bolt patterns for smallblock and 385 bellhousing bolt patterns.

The 302C and 351C are also 335 series engines but use the smallblock bolt pattern.

finally the FE and FT series include, 330, 332, 352, 360, 361, 390, 391, 406, 410, 427, and 428

Hope this clears up any confusion, Hawkrod

240 and 300 Sixes have the 302 bolt pattern. The flywheel/flex plate won't work on the V8's though, they are neutral balanced on the sixes.

Hawkrod, you might want to mention there are two 361 engines FE and FT. The FE 361 I allways thought of strange, as it was basicaly just what was later called a 360. The 361 was basically called that for two years 60/61. A 352 crank with a 390 bore if I remmember right. May have been other differences in the 361 and 360 ornot.

The FT engines are just heavy duty versions of the FE's. A 391 is the same bore and stroke as a 390, 360 and 361 are the same as each other. There are some sizes unique to trucks in the Lima lineup, though.

No need to mention it because it is irrelevant, I only made a list of the sizes it does not matter there there is more than one type in a size. there are also three 330's! Hawkrod
