I'll concede the average 6 to him. The Austin Healy 3000 is one awesome l6, and the mpg is not bad. Then again you could not shift the Le Mans Healy into 2nd without dropping the engine almost to idle, or break the tires loose. :]. I saw a nice 65 C10 Custom and the owner said he just put a 4bbl on his 250 the mpg went from 11 to 15. It was your average 65 just well taken care of, been in the family since new.

I think what we are talking about is gearing for optimum use.
