Description
Holley offers EFI Hi-Ram intake manifolds for a variety of applications, including many vehicles from the 1950s, '60s, '70s, and '80s with a Chevy small block Gen I engine. Fuel rail kits are provided and have mounting for both long and short type fuel injectors. These manifolds offer the performance potential and the appearance of professionally prepared billet and fabricated racing intake manifolds at the affordable price of a cast-aluminum product. They deliver 21st century performance for the iconic small-block Chevy engine.
* Model 300-950 is of standard Hi-Ram configuration with a "top-feed" plenum and a plenum top designed to accept up to an 105mm Gen IV LS 4-bolt throttle body, including drive-by-wire throttle bodies.
* Model 300-951 is a hood-height friendly Hi-Ram variation which has a "front-feed" plenum and a forward-facing throttle body flange which accepts an up to 95mm LS 4-bolt throttle body, also, including DBW throttle bodies. It's an upgrade replacement for the Holley/Weiand Stealth-Ram intake manifold which was a popular manifold used to significantly improve the performance of 1985-92 GM 5.7L TPI fuel-injected engines. The 300-951 system installs under the OE hood for Gen 1, 2, and 3 Camaros and Firebirds. It should be compatible with most applications with a mild cowl induction hood.
* Uses drive-by-wire or cable-actuated GM Gen IV LS 4-bolt throttle bodies
* Throttle cable bracket is supplied in the kit
* GM Gen IV LS MAP sensor port. Also has provisions for (1) 1/8 NPT, (1) 1/4 NPT, (1) 3/8 NPT fittings to the plenum
* Power band: 1,500-8,000 rpm
* Black anodized EFI fuel rails are machined for -6 AN O-ring fittings and come included with these EFI Hi-Ram kits
* Plenum top gasket type – 3/32 in. round O-ring cord
* Cast 356-T6 aluminum construction, natural, satin as-cast aluminum finish
* Requires the use of early type GM or small cap MSD or Holley distributors. Not compatible with HEI distributors
