Welcome to FTE! More than likely you do not have a 351 Cleveland because they were discontinued in the early 70s. It is possible however that someone has put that 351C into your truck, in this case it is not the original engine. You more than likely have the 351M which is for the most part completely interchangable with the 351C and 400. The timing could be different for the 3 motors however. I really am not sure what the difference would be, I am more used to dealing with my 300 I6. I would try seting the timing to the specs for the 351M and then see how it runs, you might use that as a baseline and then fine tune the engine by ear. Good luck!

You more than likely have the 351m which is for the most part completely interchangable with the 351c and 400.
You would be surprised how much is NOT interchangeable. The heads and the waterpump, and the oil pan, and a few little things.
The truck would have to have been a 302 originally for it to slide in with not much work. An original 300 six truck would work too, but the frame perches would have to be changed. An original 351m/400 truck would have needed a different tranny to fit a 351c. In all cases, the exhaust downfalls would have to be fabricated amd custom fit for a 351c.
The 351M is a member of the 'Cleveland' family of Ford engines, so that's likely what you have. From the sources I've found, 1980-1982 is pretty much a crap-shoot for what engine you might have. This is the most succinct statement I've found:
"Ford began to gradually phase the M-block out of trucks from MY 1980 through MY 1982. Beginning in MY 1980, the 400 was dropped from the engine lineup for Broncos and F150 pickups. The 351M and 400 were dropped from all but the F250HD and F350 models by the end of MY 1981, and they were dropped completely at the end of MY 1982. "
In any case, the emission sticker on the radiator bracket should tell you exactly what engine the truck had, originally.
