In an effort to save a friends life from his wife, I am now a proud owner of a complete 2.7...but I need help to try and identify it exactly since I am going to sell it so I can pour more $$$ into my 83 Cab

. Can anyone help? Also, any ideas how much it's worth? Can assume it needs rebuilding, exhaust in great shape, a few newer parts are visable, the only thing missing is the top of the airbox. Thanks in advance!
