Vacuum Packed
King Demon Carb W/Vacuum Secondaries
When it comes to street/strip machines, some of you-you know who you are-have to have yours in a large. So for those of you who say, "Super size me," Demon Carburetion has introduced a new line of King Demon carburetors with vacuum-activated secondaries, designed for Chevys weighing in at 3,400-plus pounds. When the appropriate air speed is reached, the butterflies automatically open, activating the secondary metering circuits and therefore overcoming hesitation or bogging during acceleration. The new King Demon is designed to fit 4500-style intake-manifold flanges and features a removable billet baseplate for changing throttle plate sizes. The King also comes with three-circuit fuel metering, four-corner idle, adjustable air bleeds, emulsion bleeds, and idle-feed restrictors for maximum tunability. In addition, the vacuum pod has a quick-change spring to control the secondary opening rate. The new King Demon is also available in the exclusive RS version with removable venturi sleeves. Sizes range from 795 to 1,095 cfm.

Dial It In
Pro-Billet E-Curve Digital Distributor
MSD's newest distributor, the Pro-Billet E-Curve, replaces traditional springs and bushings with a digital controller, allowing tuners to produce up to 20 different centrifugal advance curves by making adjustments with rotary dials. Factor in the E-Curve's provision for dialing in five different vacuum advance curves and you've got access to 100 different timing curves. Over-rev protection is provided by a dial-in rev limiter. The E-Curve also features a high-output ignition module, eliminating the need for an external control, making for a clean and simple installation. Connect three wires and it's ready to go.

Muscular Arms
Tubular A-Body A-Arms
The last piece of the puzzle in BMR Fabrication's A-body suspension lineup is its new A-arms, which BMR says are twice as strong as stock pieces-and 10 pounds lighter. These new A-arms are fabricated out of mandrel-bent, MIG-welded DOM tubing. The lower pieces feature fully gusseted spring cups and are assembled with polyurethane bushings and new lower ball joints. The upper arms feature new billet steel cross-shafts along with polyurethane bushings and bumpstops. They also come in versions for stock or B-body spindles. BMR's A-arms can be used with OE-style coil springs and most popular shocks, including coilovers. These powdercoated A-arms are pre-assembled with low-deflection polyurethane bushings for maximum suspension control.

Liberty Bell
621 Bellhousing
When Keisler Engineering set out to create a replacement for the hard-to-find GM 621 11-inch bellhousing, it decided to improve the design at the same time. Keisler's version uses a thick-wall titanium/aluminum casting, creating a piece that's both lighter and stronger than the original. The 621 bellhousing works with all Chevy applications using a 168-tooth flywheel and mated to Muncie, T10, TKO, Saginaw, or Richmond transmission; an alternative version mates these trannies to LS-series engines. This new 621 accepts original Chevy mechanical linkages and fork boots and maintains the original's dimensions, allowing for stock starter and header clearance. A steel inspection cover and hardware are included.

Spray Pattern
Dual Perimeter Plate Nitrous System
Need more squeeze? Zex is seeking to optimize intake charge atomization-and horsepower-with its Dual Perimeter Plate Nitrous System. Nitrous and fuel outlets are placed at 24 injection points around the perimeter of the manifold; Cryo-Sync technology is then used to inject super-chilled nitrous into the engine, rapidly cooling the carburetors and intake manifold and increasing the density of the intake charge. Additionally, Airflow Enhancement technology creates a low-pressure area under the carburetors, helping to smooth and increase airflow into the engine. The Dual Perimeter Plate Nitrous System is tunable from 100 to 300 hp and is compatible with any square-flange or Dominator, side-by-side, dual four-barrel intake manifold.
