I rather expect all the big cars were comparable within a mile or two. 8-10 in the city sounds about right if others here are reporting around 15 on the road.

Thinking back, I don't think that 51 I drove thru high school even got near 8-10--of course a lead footed teenager didn't help either.

First time I took my caribbean for a ride after rebuilding the engine, I filled the tank ran about 50 miles and ran out of gas. I didn't have the proper carbs then and was using two carbs that were used on 400s. Since that time, I put on a single carb manifold and have doubled my mileage

G'day Mates,

Time for that mileage update I promised. Unfortunately, figures were a bit over the shop but I achieved a best of AUS 19.6 mpg (US 16.3) and a worst of AUS 13.2 mpg (US 11), the worst involving some urban areas and hills. Mostly it was around 18 mpg. This is better than before the distributor was redone. The timing was set at approx 9 degrees and remembering the vac advance is now approx 20 degrees, torque seemed to be pretty good and pinging was rarely experienced. However, I'm suspicious of the carby now as there was some hestitation during the speed build up phase, although it's fine at cruising speed (55 - 60 mph). Also, the carby is "wet" around the accelerator pump area and there is petrol staining on the manifold underneath. It's off to a carby expert methinks.

Cheers, JP
