1964 Galaxie + 400M & FMX


Hi im Dave i would like to ask a few questions here . First im a die hard Ford guy always have been . The other day i was  watching a cable tv show . Some junkyard guys took a 1962 Galaxie with a y block and swapped in a 351m . Problem is like all them made for tv shows just not a lot of information was given . And this was done in the name of performance improvement . I own a 1964  Galaxie 500 that has a 390 2v c6 automatic that over heated and seized up . My lovely wife ran it out of coolant and toasted it .

Its been sitting for some time now . I never could find a replacement 390 or 428 and thought about using a 302 .

I do have a low mileage 400m 2v pulled from a 1975 ltd . It ran like a top but its not a very powerful mill . I have looked at it in the past to see if it would bolt in . I did not think it would work till i watched that show .

Now I want to use it with the fmx automatic with as little as possible overhead parts cost . And i would like to change the factory 2v to an alluminum intake and 4v holley . I did not save the dist box from the 1975 that is another problem i have to deal with . Could use all the help you can give . I know how to change that engine 390 to 390 but never did a motor swap .

I know a Little about them 400M's Kind of Like a Cleavland Engine . As for Engine Mounting if you have good Mounts on that 400 you will need to make up some Brackets to Bolt or Weld to the 1964's Frame . Also best to use the Factory Exhaust Manifolds . Have a Custom Dual Exhaust system installed . I think one of the only 4bbl Intakes that is made for it . Is the Edelbrock Performer . I would bolt a 750 Performer carb up top of that . For an Ignition System . Might be easiest to buy a after market Type with easy wiring hook up and Hotter Coil Set up .

Do you have any motor specifications on this 1975 400m looking for factory camshaft numbers ? Its a super low mile cream puff . And how much more hp will that edelbrock manifold and carburetor bring ?

1975 400M 158 H.P at 3800 RPMs 276 Ftlbs at 2000 RPMs 8.0.1 C/R

1.73 Rocker Ratio Camshaft Lift 428"in 433"ex 256 Duration intake valve size 2.041 exhaust valve size 1.654

Connecting Rod Length center to center 6.580" 4.38" Bore 4.00" Stroke


The Ford 400 engine was based on the 351 Cleveland but was produced with a taller deck height of 10.297 inches compared to the 351C's 9.206 inches.


The H.P #s above are Factory ratings yes it's a Low Compression Engine but I would say with all the smog equipment removed and free Flowing Exhaust it should Pull 230 H.P . With a Performance High Rise Intake and carb and Performance Ign . Maybe 285 H.P . But The Torque #s will be over 400 Lbs .

I believe the 400M is a square engine with a 4" bore and 4" stroke. Also the factory Ford Duraspark distributor and ignition module are very good in my experience and the module is really easy to hook up to any car with the red wire to a switched 12v and black to ground.
