Fuel economy for an I6? What's your gas mileage? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm looking at purchasing a 67 short fleet that has an I6 with a 4 speed manual on the floor and 3.08 gears. I was planning on keeping it a 6 cylinder, mainly for better fuel economy. But the owner told me that the I6 250 and 292 with the monojet carb gets worse gas mileage than a 2 barrel sbc.

I find this hard to believe so I thought I'd do a poll. To the guys still running your 6 cylinder, what kind of gas mileage are you getting and with what gears and tranny?
