1971 dart and 1969 merc cyclone

Not being a ford guy I cannot be certain but it has the bigger plugs so I was told that makes it a cleveland, but the numbers don't say either way onlly that it is a two barrel low compression 351...


On a side note I am open to trades...as well

I have a very rare 1979 Dodge St Regis if anyone is interested and it is mint, both in condition and color...only problem needs bumper fillers...which I can't find anywhere....they were removed when car was painted...but body shop could not find replacements...car also got new top....car has 318....
