Gas mileage/carb question??

[crm318]

the primaries on a holly are still larger than those on a qjet an arent as efficient. i see alot of guys ditching the factory carb on their factory motors and putting on an edelbrock or holly to fix milage or performance problems. a simple rebuild will do the trick. these carbs came from the factory for a reason from 305s to 365 hp 454s. when the secondaries kick in, they will only suck in what the engine pulls out of them. i have a 350/th350/3.08 in my 72 cheyenne lwb and i get far better milage, roast the tires until i let off the gas, and pull till 5600 rpm. i know these are bold statements, but its just something to ponder.....
