I too was going to rebuild the FMX for my 69 351W. I'm having issues finding guys that actually do it for a few reasons. 1) The parts are very hard to come by they're telling me. 2) They're dinosaurs. The c4/c6 seems to be an easier to rebuild trans, they're lighter, and can withstand some abuse.
If your guy is going to rebuild that for you, maybe I should get his info from you and give him a shout.
In a street rod or resto mod build I'd maybe not choose the FMX, I certainly wouldn't go out of my way to have one, put it that way. But it's right for this car so we might as well. No prob with the rebuild parts.
If he can rebuild an early air cooled torqueflite (1958), he can damn sure do an FMX.
It's common for everybody to say C6, but the transmission guys tell me the C4 can be built to handle HP that the C6 used to be chosen for.
