They're all very good figures, especially for 50+ year old cars with (by modern standards) poor aerodynamics.
If only we could help DWomby with his dismal consumption! If I recall correctly David struggles to get into double figures with a 360 cid engine? Makes my own tribulations seem small. I looked up the cam specs of his Mopar Performance 4452761 and they don't seem too outlandish.
So wrong timing/timing curve? Vacuum advance missing/not working? Cam incorrectly installed? Carb leak? Other leak? Fuel evaporating? Engine fault? Over-rich carb? Blocked air filter?
