i got the casting munbers off the block. its D7TEA3B...if anybody can tell me what it is i would really appreciate it

351m or 400 block...

highly unlikely to have a cleveland in an F150 from the factory.

Even more unlikely to have a 351C built using a '77 casting series truck block. LOL..that casting number told the whole story already.

351C never went in ANY Ford truck..ever..in the US. Closest thing to a truck the Cleveland ever went in would have been the Ranchero..

Oh as far as quick way to tell them APART i know the cleveland Does not have a coolant hose rinning into the intake manifold.

Neither do the 351m and 400...:toothless

While we're on the subject of the 351C vs. The 351M, I've researched them both a little further and am finding that they are more similar than I thought. So is it true that the 351M/400M were unreliable? From what I've read so far that does not seem to be true.

If unreliable means that they are known to be pretty well beat at about 250,00 miles or so..yup..unreliable they are.:toothless
