Chevy Dual Plane

The perfect match for Dart small-block heads. A boundry layer of cool air beneath the plenum and runners insulates the fuel/air mixture from engine heat. This produces a denser intake charge and makes more power. The dual plane design maximizes mid-range torque, and a ribbed plenum floor promotes fuel atomization. Recommended for 215cc and smaller intake ports Accepts popular 4150 square carburetors Dual distributor hold-downs to simplify timing adjustments Raised water cross-over and air gap insulate intake charge Integral bosses for nitrous injectors

While most manufacturers of small block Chevy intake manifolds have designed their units around 350 c.i. engines World Products has developed a very efficient manifold for 383 c.i. & larger engines that's proven to increase performance by 15-25 horsepower over the competition. In addition to out-powering the competition it's important to note that these single plane manifolds are designed to operate most efficiently in the 2500 to 7500 RPM range and have the low-end throttle response and torque comparable to a dual plane. Look inside the plenum and you'll see ...

These single-plane, high-rise intakes are designed to produce maximum power at higher rpm. Dart manifolds are designed to make engine building easier. For example, our tall-deck big-block manifolds use standard length distributors. Carburetor pads are specifically designed for 4150 & 4500 carbs. Extended runner dividers equalize port length and are radiused to equalize cylinder-to cylinder fuel distribution. Optimized runner cross-sectional area maintains high mixture velocity for maximum torque. Angled runners turn the airfuel mixture smoothly from carburetor to ports. Dual distributor ...

Designed for 1986 and earlier 262-400 cubic-inch Chevys, the Performer EPS dual-plane manifold is optimized to deliver superior performance over other low-rise dual plane manifolds. This small-block Chevy manifold has a runner design that's "tuned" for peak torque around 3500 rpm on a 350-inch engine and it produces power from off-idle to 5500 rpm. Dyno tests showed gains of 5 hp and 9 ft/lbs of torque over the standard Performer manifold on a 350 Chevy. From 3000 to 4500 rpm, the increases averaged 5+ ft/lbs. of torque for more performance where you need ...

If you are running a maximum effort S/B Chevy V8, then this is the intake for you! The Professional Products Crosswind manifold is a high performance dual plane, 180° manifold designed to be used with Holley, Carter AFB, or Edelbrock square flange carbs. The unique design isolates the plenum from the heat generated by your engine, which will give your engine a cooler air-fuel mixture and make more horsepower. RPM range is 1500-6500 Available plain or show polished Power comparable to single plane manifolds yet retains throttle response/driveability of a dual plane Cast-in nitrous ...
