400 - M

Hello, I have a 1974 Mercury Montego MX, it is a very nice car, it handle well, and all of the above. But, it has an original ford 400 2V engine. And, i can't get any real information, off the internet. Nor can i find any books with specifications on the motor. I was hoping some of the members here could give a little bit of info of what i'm Working with. Thank You.

Google "Ford 400 engine" and lots of things will pop up.

I had a 73 and a 75 when new.

Basicly it is a low compression 402 cubic inch engine with open chamber heads (about 8.0/1), retarded camshaft timing, and retarded ignition curve, catalytic converters, designed to pass the archaic smog rules.

Rated about 160 hp in the new net rating system.

Simple inexpensive upgrades that work are
a 70-71 cam timing set, which advances the camshaft about 8* and adds a noticable 20 to the power curve.
Recurved ignition timing curve with functional vacuum advance, (needs a true Ford man to accomplish)
free flowing exhaust system without cats.

If you are into cam changes, the 4x4 cam from CompCams is good.

I have a 400 M for a 76 sitting here now, in limbo, waiting for the owner's decision as to how much oooomph we are going to put into it. $$$$

Actually they are pretty good engines. They just were born (like the 400 chebby) at an inopportune time.
There have been several pretty good ones built and driven over the years. Just think if the 351 Boss or Cobra Jet had become a 400?
