New at Summit Racing: HVH Super Sucker Carburetor Spacers and Adapters
Conventional hot rod wisdom used to be that four-hole carburetor spacers improve mid-range torque and horsepower, while open plenum carburetor spacers help boost top-end performance.
HVH has turned that wisdom on its head with these Super Sucker carburetor spacers. The spacers have a four-hole carburetor base that seamlessly blends the carb bores into an open plenum at the intake manifold. This best-of-both-worlds design is proven to improve midrange and high RPM output. HVH says gains from eight to 20 horsepower are possible depending on application.
The plastic Super Sucker carburetor spacers are designed for drag race use only. The aluminum spacers are ideal for street, circle track, road race, and off-road use. They are available for 4150/4160 squarebore, Dominator, and two-barrel carburetors.
Summit Racing also offers HVH Super Sucker carburetor spacer/adapters. They feature the same power-building design as the Super Sucker spacers, but allow you to fit a 4150 style squarebore carburetor to a Dominator pattern intake manifold, or a Holley 4412 two-barrel carburetor to a four-barrel squarebore pattern manifold.
