flathead??? size???

alright.. i have a 1951 ford F-1 pickup.. 1/2 ton it has the flathead v-8.. i just was kind of curious what displacement this engine was??? and also how much are these worth?? i am wanting to get rid of it so anyone who is looking for one... it did run (3 years ago) and before i brought it out to school with me and did alot of metal work and interior to it... any help would be appreciated....

A '51 Ford original engine was 239 cubes. You say it ran 3 years ago....does it still turn over? Has it been stored under cover?

well when we bought it... it ran and we backed it into a shed and there it sat for just shy of 2 years ... then we pulled it out and loaded it up on the trailer... the alt. was shot.. and we didnt have a batt.. so we didnt try... so when it was at school we just pushed it everywhere... and as of now there is no way to see if it runs because all of the wires have been pulled out of the cab and are now in the engine compartment.. so i would assume it does turn over... but would def need an overhaul... and yes now it is back under covers untill i get more funds to start tearing into it again
