I don't think anything floats up out of that river.... It keeps it until you go get it. I wouldn't doubt something as strange as that engine being in an old truck though. I know where some plain jane F150's are with 429 CJ engines in them. I have seen warehouses full of BBC engines and 4 speeds stacked like cordwood in Georgia. A guy in Linden, TN crushed cars for weeks after the epa got on his nerves. Big blocks were scattered all over the Mountain where he lived. I saw a building in Georgia with 348's and 409's laying on top of each other. Old Man Holt in Fayetteville, TN won't tell me but I have heard from many people that he has a barn full of Hemi engines. He won't let you on his land if you are a "long hair". I have friends that have asked me to find parts on his place for him. He takes you out in his old jeep (with a chainsaw) and shows you what you are looking for. Rows of 57's, corvairs, Chryslers, Impalas and buildings with who knows what. The Chainsaw is to cut the trees out so you can get to the cars.... People are strange. There is a guy in Ft. Payne that spends his days at the entrance of his land to make sure you don't try to steal his stuff. Another 10 acres or so of cars.... Neat cars that he could retire on. Of course they are not for sale...
