Most MPG

[davidh]

I'm getting ready to swap out my 292 in for a 305 in my 67 C10. The 305 is out of a 80's camaro that was supposed to have been rebuilt. Which carb would be the best for MPG? I know the theory of 4bbl is that if you just put around in it the primaries are smaller than those on a 2bbl so you should get better mpg. But I've known some farmers who switched out to little 2bbls and claim they getter better mpg. I also have a 80's HO. aluminum intake. I think off a 305. So, I could use this and get a fresh quadrajet. I will plan on using an HEI of course too. I'd love to get 14-16mpg if at all possible. gas is going to be damn high this summer.
