Holley 300-951 Hi-Ram EFI Intake Manifold SBC
Holley designed this 300-951 Hi-Ram EFI Intake Manifold for 265-400 Small Block Chevy engines from 1955-1986. It installs under the OE hood on Gen 1, 2, and 3 Camaros as well as Firebirds, and should be compatible for most applications with a mild cowl induction hood. The versatile fuel rail kits are compatible with both long and short type fuel injectors, ensuring flexibility and convenience.
The “front-feed” plenum and forward-facing throttle body flange accepts up to a 95mm LS 4-bolt throttle body including Drive By Wire throttle bodies. This replaces the popular Holley/Weiand Stealth-Ram intake manifold, renowned for boosting the performance of 1985-92 GM 5.7L TPI fuel-injected engines.
The MAP sensor port accepts a GM Gen IV LS MAP sensor, and this manifold also has provisions for (1) 1/8 NPT, (1) 1/4 NPT, (1) 3/8 NPT fittings to the plenum. The included Black anodized EFI fuel rails are machined for -8AN O-ring fittings, and the Plenum Top Gasket Type is 3/32” Round O-ring Cord.
