if it has been a 460 all its life and in the f-250, its probably not a desirerable piece. if it were a SCJ or a CJ it might be another story. ive got a SCJ and a prepped ready to go block only went for 4700 bucks on ebay last month. but it was a saught after collectors piece. you might get 2 grand for the whole drive line if you can prove its rebuild time. , if it is stock that is. aftermarket parts drive the cost up somewhat!
