351 clevelands were built from 71-73.none of which i`ve heard being installed from the factory in trucks, all the ones i`ve seen were in mustangs and cougars. 360/390 engines from73 to76 ,351m and 400 m were installed in trucks from 77 until early 1980, the m`s or modified series of engines were low compression versions , rated at 160 hp, they really have no performance value, they are not rare, just undesirable. with a dual plane intake ,750 cfm 4 bbl carb and a cam in the 450" lift range and long tube headers , they make about 225 hp, but they make decent tourque to make up for the lack of hp, which is why they were put in trucks and large cars in the first place. if you posted the casting #s on the block and heads , i could tell you exactly what you had...i have met dozens of people that think they have a 351c in their trucks, unfortunately all of them were 351m or 400 m blocks if the 8th letter in your vin is a s its a 351, if the 8th letter is a s then it is a 400
