Smallblock efficiency or How to have your cake and eat it too

Thanks for clarifying that. I think i had better keep watching this thread because it looks like i am only getting about 11mpg (US) from my 408 W2 combo. I suppose the 3.9 gears and converter probably dont help too much but im sure it could be improved.
I have bought an afr gauge to try and get it more economical when cruising and am interested in what RAMM has to say about timing and if i should be using vacuum advance when cruising as i currently run an msd dizzy with no vacuum advance.

Sure this is no stupid question... it can get a bit confusing with all the different units worldwide. I am calculating liters per kilometer myself :)

The US gallon is 3.875 liters while the imperial gallon (UK) is a bit bigger at 4.546 liters (or litres to make it even more complicated).
And around this thread all numbers were given as miles to the US gallon... famous bob who posted last is happy to burn 30L per 100 km. No pun intended!
