The Demon 98 Four Deuce induction system (PN 9817, $2,995.95) is also available in a Six Deuce configuration (PN 9818, $3,895.95). You can also choose from red hoses and chrome fuel blocks or high-tech billet fuel rails. If you don't care for the vintage cast look, you can get the Deuces (or any of the BG carbs) chromed or powdercoated to match other components.
The Four Deuce induction system...
The Four Deuce induction system definitely takes the cake when it comes to wild looks. If manning the single carb setup has become mundane for you, this is the way to break conventional equipment.
The BadMan 675 (PN 7618, $1,995.95)...
The BadMan 675 (PN 7618, $1,995.95) is designed to provide exceptional low-speed and part-throttle driveability with the tuned runners of the AeroRam manifold and progressive throttle opening. The first and third barrels open together first, then the second and fourth open together to ramp up the power all the way to 6,500 rpm. BG designed all new metering blocks and floats to keep the fuel where it belongs, even on the baddest G-machine.

Ready for flogging on the engine dyno, the BadMan looks quite impressive sitting atop the stroker small-block. We can just picture a nice cast Shelby dual-four air cleaner on top to finish it off.
The BadMan 675 made modest...
The BadMan 675 made modest gains above 5,500 rpm over the rest of the group to take home top honors. For the best bang for the buck, though, the Mighty Demon and AeroRam is the way to go.
The last BG induction system we tried was the long-awaited "BadMan" 675. It's probably one of the most unique looking carburetor systems that you can bolt onto your Ford. On the dyno, the BadMan made its peak torque of 407.1 lb-ft at 4,500 rpm, and peak horsepower of 398.9 hp arrived at 5,800. With a similar torque curve to the 650 Demon, the BadMan stood out at the top end, offering more power past 5,500 rpm than all of the other induction combinations. In this area, we noticed that the horsepower leveled off, which probably means we've found the limit of the camshaft that we are using. Had this engine been designed for a higher rpm range, the BadMan would likely have kept making horsepower.
For this test, the BadMan on the AeroRam Intake won the horsepower race, edging out the Demon 650 carb/AeroRam combination. The peak torque "champ" was the 650 Demon on the Performer RPM manifold, though the BadMan 675 did offer a similar average number. In the end, the absolute numbers here are really a reference for a 347ci small-block engine combination. Your cylinder head and camshaft choice may offer slightly different results. After reviewing the information here, you should be able to make a better decision for that project in your garage.
