I apologize for my previous post, which was a little out of line. Don, you have the worlds best resource for your truck right here at your finger tips. More knowlegde of that motor and that truck are here than any mechanic shop or school, in my opinion. They are also some of the nicest and most helpful guys I've ever talked to, and where they have a sense of humor, I think they'll still be more than willing to help. To clarify, when they were talking about taking that truck off your hands, they were basically saying that, like most of us on here, they'd kill to have one of these old 1st gen beauties that actually under 100k miles. Your dad has a real diamond there, and with a little more understanding of our tounge-in-cheek responses on here, you'll be able to get it purring like a kitten at any rpm.
