The 600 will actually increase mileage a wee bit if you can handle keeping your foot out of it. lol Dual exhaust and an HEI will help alot as well. I used to 4 down to 2 barrel adapter on mine. When I go through the engine I'll be having a magnum intake machined to fit the 4 barrel. Putting the 600 on there so far was the best thing I did. That engine will drink the fuel though....man...lol I lugged it up a hill in 3rd almost from a dead stop and could literally dump all that fuel in it and no problem. haha No HEI either.
