I have a 59 F100 292 v8 4 spd T-98 trans, 4x4 that I wanted to re-power with a 351 Windsor.. I checked with every engine guru I could find, the answer was always the same, impossible. The swap would require a different trans and frame mounts.

I purchased an after market front cross member that would accommodate the 351 W motor mounts, the trans proved to be a problem because nobody could come up with a bell housing that would fit the T98. I was told that I would have to convert the truck to a T18 New Process.. Big problem, nobody could come up with a bell housing to fit a T18 to a 351 W.
From a past experience I knew that a 352-390 FE engine would fit up to a T98 trans because Ford offered that option in '64. I owned a '64 F350 at the time that came with a 292 V8 that had cratered, I had bought a low mileage 76 390 from a guy that had removed it from his RV vehicle to put a 428 in it's place. I went to Ford and ordered the bellhousing and front engine mount plate. We bolted the 390 into the '64 and drove it for many years.
I finally gave up on the idea to re-power the '59 with the 351W, I had the 292 rebuilt and put the truck to work.
About five years later a friend of mine game me a '71 F100 w/240 six and a T18 4 spd. As we were parting the truck out I discovered that the 240 six had the same bolt pattern on the bell-housing as the 351 W, the housing also had the two motor mount pads.
I kept the bell-housing and T18 combo just in case I needed it to repower another early truck.
