Well, in general:

The brakes will work in the 53 if you make them work.

As far as dropping the CV engine in the 53 for a start, you'll need to convert it to 12 Volt negative ground. You'll need new motor and transmission mounts - drive shaft of course. And the usual hook up mods - shift, throttle, ignition, probably modify the exhaust, radiator connections, transmission cooler.

There's probably tons more but that's a good enough start. You and 55F350 will probably get along famously.
