Hi everyone. I have a '65 f250 camper special that i'm wanting to put a 400 into. It originally had a 390 that wore out. I have a couple of questions.
My first question is, the fmx trans does it have a 14 bolt oil pan?
My second question is, is there a bellhousing that will bolt to the 400 and the fmx transmission?
Any help would be greatly appreciated.

Thanx Joe

 

390's (360's) not installed until 1968, 1965/67's only available w/a 352 2V.

Since all FE engines look identical, and many sellers are clueless, on sale day, 352/360's magically become 390's!

FMX introduced in 1969 Passenger Cars, used thru the mid 1980's. Only trucks it was installed in were 1973/77 F350's w/300 I-6's.

1965/67 F100/350 352's came with MX Cruise-O-Matic / 1968/76 F100/350 360/390, 1977/79 F100/350 351M/400 came with C6's.

A/T's have converter housings, bell housings only used with M/T's. C6 converter housing made as part of trans case.

C6 used with FE engines different than with any other engine.

IMO, there's far better choices than the 400, especially if a 1974/82 version, as it and 351M's were smogged up terds very prone to cracking cylinder heads.

 

I agree with numberdummy, you can get an engine like a 302 351W or 460 cheap and have lots available aftermarket support, you can build a stout 400 but for the same cash put it into something with more accessible parts. I believe the 351M/400 has the same bellhousing pattern as the 460. So you could find a C6 from a 460.

thanks guys. I know the 400 wasn't a very good choise, but i have one out of '79 bronco that has been rebuilt within the last 5000 miles. The 390 that was in it is far and gone the auto trans I still have not exactly sure what it is though. It has 14 bolts holding the pan on and the converter housing (thanks numberdummy for the correction) is seperate from the trans housing. Have been told a C4, fmx, and also a C5. The C5's didn't come out until the '80's and I know the trans has been in the truck since the early '70's so it can't be the C5. Correct? But it was the only trans that had a 14 bolt pan? Thanks again guys.

 

Here are the bell housing patterns for the C6. The top one (SBF) includes 221, 260, 289, 302, 351W and 351C. It also includes the 200, 250 and 300 I6 motors. The center one (BBF) includes 351M, and 400M but also includes the 385 series motors 370, 429 and 460 which is missing from this picture. The bottom is for all FE motors from a 332, 352, 360, 390, 406, 410, 427 and 428.

Im with ND and dman, skip the 351M or 400M and look for a 460 if you want a big block, or go with a 351W if you want a small block. Parts are cheaper and more available and performance are much better with these two motors.

 

The BBF "385" series bell pattern is used by the 370, 429 & 460, as well as the 351m/400. (some '73 400s have the SBF pattern and used the FMX trans. Pic here:

The 351C and 351W use the SBF pattern.

To the OP: 14 bolts are found on the FMX. Iron case with separate bell and aluminum tailshaft housing. Pic here:

AOD, AODE, 4R70W also use 14 bolts. Check the patterns and shapes of others here:

What trans was in the Bronco? What truck did the 14 bolt pan trans come out of?

 

Ok it looks like the trans is a fmx. The trans that was in the bronco is a manual trans with transfer case. The trans has always be in the truck that i know of. I starting to think that i'd be better of just putting a 390 back in the truck. Maybe be a good time to use the set of SCJ 428 heads i have and just build a nice FE for the truck.

 

MX (big Cruise-O) has 14 trans pan bolt holes and a pronounced notch in the pan that FX (small Cruise-O - also 14 bolts) & FMX's (14 bolts) do not have.

Therefore, the MX trans pan and gasket are different and so is the filter.

 

Yes, my mistake. Was happily typing away and typed the wrong thing.... The 351C is a SBF bellhousing.
