My friend up buy Phoenix says he could get that sort of mileage out of his old 273's as well. None of mine get close to that. The Coronet 318 was built 100% with FiTech fuel injection and a 2.94 gear... 13 MPG. The Duster 318 has a carb, Toth heads but has been AFR'ed to a nice tuning and it gets about the same with a 2.94 gear. The Valiant is the 360 with Edelbrock heads that also has been AFR'ed to a nice tuning with 3.21 gears and it gets about 12 MPG.
