Just for the record of carb performance, I calculated my fuel mileage over 1711 miles driving to the Reno Rally. The engine is 484 hp 351C with a Holley Strip Dominator intake, CR 10:1 ported 4V quench heads, and a custom Holley 4150 double pumper. The run to Reno included many miles of high speed grand touring driving.
The calculated miles per gallon was 18.7 mph. 17-19 mpg can be done---perhaps not often and more often with custom carbs, but it can be done.
Warmest regards, Chuck Engles
I doubt that my 550 horsepower 390 cubic inch stroker engine would be able to get more than about 15 mpg with a carb. What I do like is that I can go from sea level to 9000 feet above sea level and never worry about how the car will start or run. For most Pantera owners the switch over to fuel injection will never pay for itself in increased fuel mileage. The aftermarket fuel injection systems have come a very long way from the time that they were first on the market. Some of them were definitely very bad, but those days are long gone.
