I am new to this forum so first allow me to offer my thanks for all of the things I have learned while silently browsing. I already own a 1966 Chevy PU/327/4 speed that my father gave me and I love it. I have always wanted a 67-72 Chevy as well but just never thought I would find myself in front of one with enough money to cover the cost. Well, last week a co-worker sold me a 68 that he had just purchased from a small town fire department last year where it had been garaged for decades. He semi-restored it by taking it apart and repainting the frame and then the body. It has new rubber, new radiator, new Edlebrock 650 carb, new battery and new alternator on a 350 with about 10,000 miles on a rebuild. The truck came with the original owners manual, protectoplate brochure and records for everything that had ever been done to it. (The 350 replaced the engine the Fire Chief blew up, too bad.) I will be repainting it, putting on some new rims and replacing the steering wheel with an original but that is about it. When I am done it will become my daily driver. I do have one quick question - what is the best mileage I can get out of a 350?
