Carb recommendation

Im looking for a new carburetter to replace an old Holley vac sec. 600cfm #1850.

i currently have a 300bhp 302 that is purely for the street use.It has big valve heads, 9:1 compression ratio and a street cam .I want a manual choke and something less than $400. It needs to be street driveable with good gas mileage on low throttle settings. People have recommended the Holley 4150 Double pumper or the street avenger . How do these carbs compare in terms of gas mileage and horsepower over my old 600cfm set up ?

Any recommendations?

YOU ARE POSTING IN THE TRANSAXLE/DRIVETRAIN SECTION, YOU MIGHT WANT TO PLACE THIS IN THE PARTS OR SERVICES WANTED SECTION OR THE ENGINE SECTION!!! YOU MIGHT FIND BETTER LUCK THERE.

BY THE WAY I WOULD RECOMEND THE STREET AVENGER SETUP, EASY TO TUNE AND CHANGE JETS AND I AM RUNNING A SIMILAR SETUP ON A 9'' LIFTED BRONCO, RUNNING A CRATE 302 FROM FORD RACING WITH A GT40 VALVETRAIN AND IT'S GETTING ABOUT 9.5-1 COMPRESSION. IT TURNS 38'' TIRES THROUGH AN AUTO C6 AND I AM GETTING ABOUT 9 - 12 MILES TO THE GALLON ON 4.56 GEARS, YOU WILL PROB GET BETTER GAS MILEAGE LOL!!!!!

THE DOUBLE PUMPER 4150 IN MY BELIEF IS A BETTER CARB TO TUNE FOR MORE PERFORMANCE, MORE AFTERMARKET MAIN BODIES AND OTHER SUCH TRICK THINGS. I WOULD RECOMEND IT OVER THE STREET AVENGER ONLY IF YOUR EXPERIENCED WITH TUNING CARBS AND DESIRE MORE PERFORMANCE, THE STREET AVENGER IS AN EASIER CARB TO DEAL WITH.
