Stock 340 intakes

Well it has 3.91 gears, 27 " tires., stall converter is a higher stall "police special", trans guy said. I think its like 1800, it was cheap, under $100 and gas was too back then.

Headers, a 268 comp cam HE, my carb right now is a holley 750 but found a Carter 600 for it-scare gas is going over $4 this spring.

My mileage has been stuck at 10 mpg, I do drive it hard but also hear of some 340's getting 13-15 mpg, if I could just get 12 mpg that be 20% better than now

Its not my daily driver but like to drive it, when gas was cheap-under $2- I could put a 100 miles on it in 1 day.
