The FMX transmission will bolt to a stock truck automatic bellhousing with some work. It's been documented and is described on other y-block web forums.
Some people will deprecate the FMX but it lives behind many high torque engines like 390's and 351C/4V. If I am recalling correctly, it has the advantage of being able to be push started if your battery goes dead. Most other automatic transmissions won't do that.

The FMX conversion uses some CruiseO Matic parts.
Nothing wrong with the FMX except weight, Summit even carries a performance kit for it.
I ran one for years behind a honkin' 390 and never a problem, even towing a loaded car trailer.

FMX is a heavy dependable transmission that will handle severe abuse in a drag car. Only drawback is weight. I will be using it in my 57 F100. You can use factory mounts, shifters, linkages, driveshaft, speedometer cable, etc................
