Here is my vin OF05M186073 ,all original . What is do I have a 351C or a 351M and what is the differance? Yes I'm new at this:laughlitt
You have that backwards, 1970 was the first year of the Cleveland, and Ford was phasing out the windsor with the Cleveland in cars, and the 351-400m in trucks. Fords entire plan was to axe the windsor entirely but due to insurance, emmissions, and fuel economy they reversed the decision later in the '70sAre you sure it isn't a W? In 1970 Ford was phasing out the Cleveland (C) to replace it with the Windsor (W). It's going to be either a 351C or 351W.
Not true. All 351's have the same bore and stroke (4.00x3.50). The M's had a taller deck height and a longer con rod.Just to clarify though, 351Ms were primarily a truck motor (or large car motor) They had a larger stroke and smaller bore for better torque characteristics. Also all had identical heads to the 351c 2V, none were 4 barrel
The discussion was on 351 Modifieds (351M) vs 351 Clevelands (351C) an M code cleveland is still a 351C.Yeah, its on wikipedia, M code means 351 cleveland 4V, good engine, I've got two of them sitting in my garage
