1971 ford 400M with C-6 powering a 1959 Fi100 Custom Cab

Morning folks, I just joined, from the hinterlands of far west Texas, rural Hudspeth County, 80 miles east of ElPaso, to be exact. I have a 1959 F-100 Custom that is all there, with a 292 and T-98 of unknown condition, other that it has not been started in 20 years. I picked up a unregisterable 1971 LTD with less than 7,000 miles on it that has been in covered but not enclosed storage for ten years. It is powered by a 400M and C-6 tranny.I got the vehicle strictly to put it's powertrain into the F-100. Any advice other than to use a different powertrain would be welcome.
Thanks.

It has pre smog compression, the 2 BBl Holly, a points type distributor which I actually prefer, A non-computerized transmission, and front disc brakes. I'm not sure about the rear axle, and won't know till I bring it home next week. As soon as I bring her home, I will pull the plugs, and throw some MMO down the cylinders. I am an active pilot, and have an engine pre-oiler with oil heating elements that I will use to heat and pressurize the oil in the engine.
