----Funny part of the 2-barrel set-up was that the 2-barrel got worse mileage than the Quadrajet under normal driving. Quadrajet primaries being so much smaller than the two-barrel helped!......Bill S

That is something. Yes you would think the 2 BBL would get the mileage but didnt according to your info. Probably because people had their foot in the gas more in the 2 BBL to give that engine more power, just my guess.

Reminds me of my fathers first Suburban, I begged him to order that 73 half ton w/a 454, he thoughtI was crazy because his Travelall he was replacing only had a 304! When 78 rolled around and it was time for another Suburban , it was a Big Block and it gave almost 3 MPG better than that Small Block, and he could tow again.
