Finally got my car out for a cruise, first for this year. Over the winter I tuned up the motor, re build the 780 Holley, got the timing dialled in. Curious what mpg this car gets,( not that it really matters) I filled up with 94 chevron until nozzle shut off, drove conservatively for 46km/29miles, cruising 50-60 mph with about 5 stop lights. Pulled back into the same chevron and filled up again same way could not put anymore fuel in..it took 3.6 litres/.92 us gallon, which is 31-32 mpg or 7.5l per 100km. I have a 700r4 with 4.10 gears. Anyone else achieve these numbers? I realize it’s high for a 50 yr old performance engine, I would not have believed it without seeing for myself.
