The engineers at Weiand recognized that today's engine technology has really advanced in our performance world since the "Stealth" series intake manifolds were originally designed some years ago. But consider this: Given a dual-plane intake with efficiently flowing runners, the carb flow seen by any one cylinder of the engine is half of what it is on a single-plane intake. Find Wilson Manifolds Tapered Carburetor Spacers 004110 and get Free Shipping on Orders Over $99 at Summit Racing! Wilson Manifolds tapered carburetor spacers feature a computer-generated, variable-radius taper design that maximizes airflow through the carburetor and enhances air/fuel distribution for more horsepower. Package seven also needs port velocity like an Edelbrock RPM intake or smaller single plane intake but makes good power. HVH-SS-4500-4150-2-AL 2” Tall aluminum Super Sucker spacer adapter for 4500 series carburetor to a 4150 manifold. 00 After many years in the remote manifold wilderness, Windsor owners have a true choice in intake manifolds for their 351 to 400+ cubic inch engines. Sheet Metal Fabricated Intake Manifold LS1/LS2/LS6 Single Plane EFI + Fuel Rail Kit Black with Sniper EFI logo - Now includes mounting provision for MAP sensor on rear of Intake plenum. James,MN for ride specification, modification info and photos and follow F100cleveland's 1982 Ford F150 Regular Cab for updates at CarDomain. When our 492" FE first went on the dyno, we were keen to use a dual plane intake manifold if possible, to maintain the sleeper appearance of the engine. Single plane intake -vs- Dual plane intake The charts below shows the torque and horsepower advantages between the two intakes used in the dyno test shown above. Edelbrock "Air Gap RPM" Dual Plane Intake the same blueprint work is done and we dyno test it on a comparable engine to yours before it ships! Carb Spacer. So what can we do to get a bona fide 400 hitting the ground? Well it may not take more than an intake manifold. The original manifold (produced in both cast-iron and aluminum) is a dual-plane (180°) design, still available from Edelbrock as CH-6B. stands behind each product we manufacture 100%. Additionally, there is the Weiand three deuce intake WPD3D; same single plane design but with square carb mounting pad for later model four bolt flange carbs. During the dyno test and tune, we will be trying out some spacers, but for now, this carb is ridin' commando. Run on the 347 with the dual-plane Performer RPM intake, the little stroker produced 434 horsepower at 6,200 rpm and 412 lb-ft of torque at 4,400 rpm. The Hot Rod 400 Ford on the Dyno we didn't have the time or money to try a single plane intake, which I think would have produced a big jump in peak horsepower. The manifold can be used with ported factory cast iron 289, 302 or 351W cylinder heads, or aftermarket aluminum heads. Theory, Application, And Testing Of The Wilson Tapered Carburetor Spacer. The larger carburetor reduces venturi airspeed, allowing the air/fuel mix­ture to make the turn into the run­ners more easily and with less fuel separation. secondary carb, the older Comp 274XE cam and 1-7/8 headers. The theory with putting the reed spacers on the carb side of the reeds, thus spacing the manifolds back slightly, is that you increase the velocity of the intake charge, typically looking for gains in upper RPM power. Our test platform details for Holley HP EFI dyno run: Dart 440cid engine, 10. The intake manifold port exits match up to these heads with little or no matching required. Ford Windsor Commander Manifold $970. Blue Thunder Dual Plane Intake with Different Plenum Divider and Spacer Combinations. Should I Run a Carb Spacer? Carb spacers only do one thing, increase the size of the plenum area of the intake manifold.
