The Holley EFI 300-652 intake manifold adapter plate enables the installation of Gen III Hemi Hi-Ram intake manifolds on early small intake port engines. This precision-engineered adapter bridges the gap between modern high-performance intake systems and classic engine platforms.

Key Features:

  • 0.945-inch thick billet aluminum construction for superior strength and durability
  • CNC-machined for precise fitment and optimal sealing
  • Allows Gen III Hemi Hi-Ram compatibility with early small port engines
  • Complete hardware and gaskets included for straightforward installation
  • Corrosion-resistant aluminum construction withstands high temperatures

This adapter plate provides an ideal solution for engine builders and enthusiasts looking to upgrade to modern EFI intake manifold technology while maintaining their existing engine block. The included mounting hardware and gaskets ensure a complete, leak-free installation right out of the box.
