Good morning all,

Just wondered what sort of ball park fuel consumption figure I should be getting from my Amazon, its a 1970 121 B20b that has been converted to twin carbs (SU's) and its had some engine tuning work carried out in the past, it has a non-standard cam but I'm not sure of its spec and I have a dyno print out recording it having a max bhp of 142 at the flywheel so with that in mind I'm aware it will use more fuel than stock but was hoping that someone might have a car in a similar state of tune and be able to feedback some figures?

Thanks in advance Doug.
