thanks:

 

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!

 

yeah i am sure its not a 351 cleveland. The 351m looks similar but thats it. Try using 10 btdc. It could be a windsor also.

 

Here's a list of some ignition timing specs for 351M/400 truck engines:

Try posting in the "351M, 400, 351 Cleveland" engine forum for more help with the engine.

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.

 

This site has a great table of what's interchangable/what's not:

Yes I have three uncles who worked for ford from 1978 to 2011 and you're not correct about the 351 Cleveland been discontinued in the seventies it was not discontinued until 1983 in America however it was continued to be used in Australia up until 2001 I have an 80 f150 4x4 and it came from the Ford plant in claycomo Missouri with a 351 Cleveland

 

You are aware this thread is 17 years old right....

 

351C US/Canada: 1970/74 Ford/Mercury Passenger Cars & Ford Ranchero. Not installed in anything after 1974, never installed in trucks.

What's the VIN of this F150 4WD? The only Ford assembly plant in Missouri is located in Kansas City.

 

You know the Kansas plant is not actually in Kansas City, but just North East in Claycomo right.

And if the trucks were built for the AUS market they likly would have been fitted with Geelong cast 351C's at Kansas. The 302C/351C were used down under in trucks till 85 or so.
Below is a 351C equipped 81 F150

 

That's why I said US/Canada, because 351C's were not installed after 1974...for the US/Canadian market.

If Kcak47mopr posts his trucks VIN, the truth will be evident for all to see.
