Product Details

The Holley EFI 300-242 Hi-Ram EFI intake manifold is engineered specifically for 351W Ford small block engines with a 9.5-inch deck height. This high-performance manifold system delivers improved airflow and fuel distribution for EFI-equipped Windsor engines.

Key Features:

  • Designed for 351W Ford engines with 9.5-inch deck height configuration
  • Compatible with 95mm or 105mm GM LS throttle bodies for flexible performance tuning
  • Integrated EFI fuel rails machined for -8AN O-ring fittings with large internal passages
  • Fuel rail design helps dampen pressure pulsations and accommodate high-flow fuel systems
  • Plenum top gasket uses 3/32-inch round O-ring cord for reliable sealing
  • Requires Holley EFI Dual Sync Distributor (Part #565-111) for proper engine timing control

This Hi-Ram manifold combines the performance benefits of a high-plenum intake design with modern EFI technology, making it an ideal choice for street performance and racing applications. The manifold's fuel rail system comes standard with the Hi-Ram kit and provides consistent fuel delivery even under demanding conditions.
