Inliners International Forums General Discussion Engines Question regarding fuel milage between 292 and 250 chevy engine??

If you're getting 18, that sounds pretty good for your vehicle. I had a 1936 Dodge sedan with a 250 and it got 20 mpg with a 200-4r auto OD and a 3.00 rear end. I put a 292 in it and it went to 18. I don't think you can do much better than you are. Joe
