12mpg rolling empty road trip, 55mph is. 402bbc

V6 7.5mpg uphill, down hill, hauling water.. it just liked fuel. But since designed in late 50s, looks like ports from a 348...anchor, neither designed for fuel economy, but fuel was cheap. Massively heavy built, designed for durability. My old V6 is going in a 67 4x4 restoration, his block was cracked. Win-Win
