any good Cleveland core is worth a couple hundred bucks. Not really going to be worth much more then that. I had a rebuilt one I sat on for 3-4 years trying to get what it was worth. Ended up finally loseing my *** and taking $600 for it. A running one might be worth 3-4 hundred to the right guy. There just aint a big demand for them. They were in so few cars for such a short time. Fords most underated engine.

depends on whether or not it's really a cleveland, all the 351M's sold as clevelands really killed the market.
if you find someone desperate for that engine and your numbers match then it could be worth a couple hundred

i dont know what there worth but you can get alot of power out of them. my dads old 79 f250 had a built 351 cleveland special. 36" bfg mud-terrain tires, 4x4, 3.73 gears, weighed 6300lbs with him in the seat. that truck ran 13.5 in the quarter mile and still got 13mpg when he stayed out of the throttle.
