The 4000 is a pretty awesome find. I picked it up at a nieghbors auction one mile from my house thinking I was going to use it as parts truck but it was so solid ,Ive switched gears from restoring my 62 one ton to working on the big boy. I have a masonry company here in frederick and hopefully will use this as a part time work truck, part time show truck. The truck came with a optional 351, two speed rear and I think the longest wheelbase 223" . The only bad is the two fenders are a little mangled. But shouldnt take much to fix.
