400 FMX
#1
When I talked with the owner of my car, he made it pretty clear he was not a mechanic or up on Mach 1's. I had him take pictures and knew the engine was not the original by the 2v Weiand intake. He thought that was factory because he was told all Q codes had aluminum intakes.
When I pulled the motor out, I found that it was a rather rare D1AE-6016-A2C 400 FMX Block. These blocks were only cast in 1973 and what made them unique was the fact that they had bosses in the block that could be tapped to put them in anything from a pantera to a pick up. The back of the block also had both sets of holes for either a C6 or FMX depending on where it was going.

What was sad was when it was put in my Mach 1 they didn't know what they had and that all that was needed was to drill and tap the block bosses for a 351. They just saw the 400 motor mounts and here is what they did. Measures 7 inches X 5 inches X 1-1/2 inches. Good thing I'm replacing the front frame or I'd have been really mad cutting those suckers out.     Huh

I have not personally seen one but according to my reference materials, the D3AE-B for the 1973 400 CI motor was the one that is considered rare. The rarity is based on the fact that this particular 400CI block allegedly has the same bell housing pattern as the 351C.

The D1AE-A2C, along with the D1AE-A, D1AE-AC, D4AE-B2A, D5AZ, D7TE-A2B and D8xx were made between 1971-1980 and all supposedly have the Big Block (429/460) bell housing pattern and big block motor mount bosses.

The one pictured looks like a small block bolt pattern to me.

...and you guys appear to be ABSOLUTELY correct as I see "it" now! The approximate 1" higher deck height to where the bosses (presumably) are is evident in the picture and supports the "multi-tasking" theorySmile.

It actually looks more like it has the small block bell house pattern with the "bosses" for a 351M, regular 400 or 429/460. According to another of my references, these were apparently installed in full sized Fords with the FMX transmission.

Is the code on the FMX transmission "PHB-AD?"

Yes, that is one of the things that is "throwing me", the casting number. Supposedly, this particular (hybrid?) block was only made for the one year (1973) which makes one believe it should have a D3 number.

That is why I was asking about the casting number on the transmission.

Very interesting subjectSmile!

Do a search for "400 FMX", and/or email username "blizz" (blizzard ND). He has one in a first generation Bronco and is fluent in Clevelandology.
