I have a 1940 Ford coupe and a 351W with a FMX transmission ( out of a Mustang) that I would like to put together. Does any one know if the FMX will fit into the unmodified X-frame of the 40; or have experience in doing it?
There's a small block Chevy and TH400 in it now, but we'd like to make it an all Ford machine. Thanks !!

moving to basics ,

see if more answers for the member's question.

I don't think any transmission will fit into an unmodified crossmember on the early fords( or Mercs either). There's a reason they sell kits to modify them, the original tranny is miniscule compared to virtually any modern tranny 3spd,4spd or auto. If you are unwilling, for whatever reason, to remove or modify the X brace, you have limited options in transmission choices.While the FMX is a nice strong tranny ...it is not small by any stretch.

No it won't. I do own a 40 ford coupe and my X member is been widen for the 700R GM transmisson alone with custom made Transmisson mount. Plus you will have to split the wish bone and bend the out to meet the X member rail. I put a hime end along with an adjust bracket so you can adjust the caster on the straight axle along.

Woodz & Racecar ; Thanks for the input! This is all new to me, but I should have said originally that the 40 has a Chevy small block and a TH350 in it now. Sooo.. with what you guys have said, it maybe a modified X-member. I'll have to get it up in air and check that wishbone, and get some real measurements. I appreciate the time you each took to help me = thanks again. John

I have installed a SBC and a 700r4 tranny in my 1940 Ford Coupe. I have enclosed a few pix for your evaluation. These are early in my modification process. Hope they help.

I guess that my choice would be a nicely modified C4 rather then an FMX. There are many upgrades possible, weighs a lot less and is a heckuva lot smaller. The C4 will bolt up to the back of a 351W but you will need a torque converter and a flex plate. both of which are reasonably priced from Summit (TCI parts).

This is a 302/5L, but essentially the same rear of the engine dimensions:



It is a TCI Street Fighter trans, Super Street Fighter torque converter, SFI flex plate, servo cover and kit and a Lokar shifter

There's a few pics in my journal of my 36 frame, (same, 35-40) to get a few ideas. My buddy that built the frame uses the same concept for Ford running gear. good luck with your build, keep us posted.
