So you've got a high horsepower engine that needs more cfm but you are stuck with a 4150 intake manifold. You've tried an adapter to fit a Dominator 
style carb but it barely gained or even lost power.
Our flow tests revealed that when using a 4150 intake manifold and utilizing an adapter to allow the installation of four barrel Dominator style carburetors on 4150 intakes, the cfm can actually end up flowing LESS with the Dominator style carb.
This is because air is lazy and will mostly draw from a central area of the 4150 intake manifolds opening. As a result very little air flows from the outside edges of the venturis of the new bigger four barrel carburetor. So this adapted attempt to increase cfm actually gave you less cfm or a very minimal gain in flow of air to the engine.
This is not so when using an SV1 and our NEW Part # 7760 adapter.
The larger 110 mm blade equipped SV1 with its centrally located air inlet (unlike a four barrel) will only require a small amount of air redirection when adapted to fit onto a 4150 intake manifold. When used along with our 7760 adapter, this combination offers a smooth transition of air flow to the opening of your 4150 intake manifold. This combination will NOW show us the proper and expected increase in power. This minimal redirection of air will also give us incredibly high rates of engine acceleration in the real world.
Granted our smaller 95mm blade equipped SV1 will bolt right onto your 4150 intake manifold (no adapters required) and will flow over 1100 cfm. But if you need more air, we got you covered. If want to achieve 1300 or more cfm of flow from your 4150 intake manifold, our NEW part # 7760 adapter and the bigger 110 mm blade equipped SV1 is the way to go.
Many 700 plus h.p. engine programs that utilize 4150 intake manifolds will show typical gains of 20-40 h.p. when switching from a 4150 series carb to an SV1 and our new 7760 adapter.
In tests using an 110mm blade equipped SV1 as a base, the 7760 adapter ALSO shows an average 5 h.p. increase in power over using a conventional 2" tall Dominator to 4150 type adapter. The 7760 adapter is only 1" tall, so its shorter and makes more power too. Its a win, win.

kit includes the distributor, wiring harness, connectors, ballast resistor, instructions and an orange control box. The distributor features a high performance advance curve and comes complete with cap and rotor. Replacement distributors, control box, wiring harness and ballast resistors are available separately. 
packages. The “Ultra Lites” were designed for maximum strength while providing the lightest possible spindle for the factory style suspension Mustangs and Camaros. The “Ultra Lites” were designed to offer the ultimate in weight savings for drag racing applications requiring the braking power provided by a 4 Piston caliper. This Spindle is designed with a 7/8" Longer Steering Arm to accommodate forward mounted steering racks such as our Stilleto Series K-Members. Steering arm has also been lowered 1" to help eliminate bumpsteer without all of those unsafe spacers typically required on a stock spindle at a lowered ride height. Also utilizes our 7/16" Lightweight Bumpsteer Kit.
design envelope. CNC machined runners and combustion chambers achieve flow numbers nearly on par with the Victor series professional race head, while maintaining compatibility with off-the-shelf or even stock components including headers, pistons and rocker arms. The deck has been rolled 1.5° to improve the intake valve angle and consequently port velocity, while ensuring that the 2.25" (oval) / 2.30" (rect.) intake and 1.88" exhaust valves will still clear the factory valve reliefs. The exhaust flange has been raised less than 1/8" to improve flow around the short turn without causing conflicts with off-the-shelf 2" primary tube headers designed to work with stock heads. The 300cc (oval) / 325cc (rect.) intake ports and 110cc chamber volumes will ensure that the performance potential of these heads is sufficient for nearly any street driven application. The rectangular port heads are even available with a larger 118cc chamber to support forced induction and pump gas friendly compression ratios.
accessories. Chrome engine parts are easy to install, easy to maintain and easy on the wallet.
