I have a 69 Coronet with a 440. It was a 78 low compression block that I built, mild cam, stock intake, headers...nothing to brag about, but a solid driver. I have a rebuilt Edelbrock 750 on it, and it gets terrible gas mileage,less than 10. Its also a dog, I hate to say, takes forever to build power, but once it does, its quick. Should I dial down to about a 600 cfm carb? Was going to upgrade to a aluminum intake from Summit, and ran their carb calculator. Whats everyone runnin?
