Jack.
Nah. You can call me that. Or just J. Or Jim...

Anyway, I don't think my son has ever checked the mileage on his sedan, but my coupe gets about 18.5 on the road. Probably 16 or so around town. It's not great mileage, but I've had worse. My engine is a .030 over 350 with hypereutectic flat top pistons and some old open chamber (76 cc) LT-1 heads (1.94/1.60 valves). Intake is Edelbrock Torker II with an old Quadra-jet carb. The cam is a Crane Energizer. I don't remember the specs on it, but it was the most radical cam I could use and still keep the stock torque converter. The transmission is a bone stock Turbo 350 out of an early 70s Monte Carlo and the ignition is an old fashioned points/coil distributor.

Probably, if I put a dual plane manifold on it with a freshly rebuilt carb, HEI ignition and maybe a different cam, I could boost the mileage some...
