A Corvette has about the same EPA rating as the 300C, but has an annoying

thus improving the fuel mileage on the EPA tests, but not in real world.
And its 6 speed transmission has two overdrive ratios, as opposed to the
300C's 5 speed and one overdrive.

No one uses the 6th gear in a Vette except maybe on long highway runs
where you get good fuel economy anyway. The Hemi according to some
users nets about 14mpg or less, depending on the vehicle.
I figure my Mach-1 gets worse mileage than the current Corvette.

That was my point, the 6th gear on the 'Vette only really affects the EPA
ratings, since the highway mileage tests are done in that gear.
And that 14mpg figure is probably for the trucks, which don't have the
"Displacement on Demand" feature. I've heard that figure bandied about for
the Ram, anyway. Car and Driver got something in the neighborhood of 20mph,
IIRC, during their road test of the 300C, which includes their acceleration
runs, handling course and braking tests.
And I'm sure your Mach I gets worse mileage than most of the performance
cars on the road today, electronic fuel injection and electronic ignitions
are much more efficient than the old ways.
