Holley LS Modular Lo-Ram EFI Intake Manifolds

Holley LS Modular Lo-Ram EFI intake manifolds are designed for GM LS Gen III and IV engines equipped with GM LS1/LS2/LS6 (cathedral port) cylinder heads. These intake manifolds will work with OE or aftermarket cylinder heads. The Lo-Ram intake manifolds are designed for forced induction (supercharged or turbocharged) engine applications and a 105 mm throttle or similar models. The base intake manifold is designed with a lower overall height to fit under a stock or mildly modified hood in the front-feed configuration. The modular design allows the use of front-feed plenum entry, while intake design facilitates custom inlet duct and throttle body placement. Additional features and specs: * Cast aluminum construction with satin silver finish * Modular design allows the use of front-feed plenum entry * Clears 4th Gen Camaro and C5 Corvette cowls and hoods without modification * With forced-induction and the short runner length the engine rpm at which peak power occurs is more likely to be coupled to the supercharger or turbocharger being used * High-volume fuel rails and mounting hardware included with 3/4 in.-16 O-ring ports (8 AN) * Fuel rail kits include two sets of brackets; a set for long (usually standard length) fuel injectors and a set for short (such as Pico, or LS7) fuel injectors

Edelbrock Super Victor Intake Manifolds

Edelbrock Super Victor intake manifolds are arguably the most popular and flexible manifolds in racing today. You'll find these single-plane manifolds on oval tracks, in drag racing, and on NASCAR engines--anywhere that maximum horsepower and torque are needed. The extended, constant cross-sectional area of the runners produces more torque across the midrange--from 3,500 up to 8,500 rpm in most instances. So, they deliver great throttle response off of the corners in oval track racing and improved 60 ft. times in drag racing. Their direct "line-of-sight" flow path provides maximum flow and there's plenty of material for port matching. They're also ideal for alcohol use.

Holley EFI LS Hi-Ram Intake Manifold Bases

Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.
