I have an old 1988 Linclon Town Car with a 302 engine and an AOD transmission. My land yatch will get 20 MPG on the highway and it has way way over 150000 miles on it. I have considered putting this engine combination in my truck before because of this example. So don't worry about it 35Chevy. I am so tired of see SB350 engines that the 302 may be a welcomed sight. I liked 2ManyToCounts comment, no one would have said a word if it was a Hemi.
