Holley has announced the release of two new intake manifolds from its Holley EFI division – these modular Lo-Ram intake manifolds are designed for cathedral port LS engines and can be configured for turbocharged and centrifugally supercharged applications.

With a peak power limit of 7,000-8,000 rpm, this ultra-low design is perfect for any high-revving LS engine stuffed into a small engine compartment! These intake manifolds will work with OE or aftermarket cylinder heads and a 105 mm throttle body such as part # 112-581. The fuel rail kits come with 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.

300-620 Top-Feed
The 300-620 top-feed plenum entry configuration is designed to allow the currently available Hi-Ram 105 mm plenum tops to be fitted to a low-profile base intake manifold. The short runner, low-profile base intake manifold intended for forced induction applications was conceived to package with an air to water plenum mounted intercooler with a shorter overall height than possible with other existing intake manifolds. Using a modular design, the top-feed plenum configuration with 105mm top keeps the overall height at just 9.07″!

300-621 Front-Feed
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. It will clear a 4th generation Camaro and C5 Corvette cowl without modification. The front entry plenum allows the design and fabrication of special throttle body adapters and/or inlet ducts for custom installations. The high volume fuel rails utilize 8 AN o-ring ports and include mounting hardware. Overall height with the 105mm throttle body adapter is 6.86″.
