my Nova routinely got 17 mpg with the Vortec/HOT cam/T10/3.70 combo.
of course, i had a qjet and a performer intake.

probably low double digits with normal driving habits, which of course we all know will never happen. I have never even attempted to gauge my 302, but would guess 8 mpg at most, 3:73 and m21; anyone really care about gas mileage anyway?

I thought my H2 was bad at 10mpg...Than I put my 69 back on the road...I'm lucky to get 6. (3.73 at 2600rpm) If I put my foot in it...The gas gauge and the Tach go in sync. The tach goes up..and the gas gauge goes down. My dad, who built my motor for me just laughs. He tells me that I told him I wanted a bad boy..and he gave it to me.

high performance does not have to mean low mpg.
and high mpg does not have to mean low performance.
