The Hilborn EFI-R injector manifold kits combine the technology of Electronic Fuel Injection with the racing born performance and aggressive looks of Individual-Runner engine induction. The engine valley covers are sold separate to allow the customer to choose the correct valley cover kit based on the engine deck-height, 300-802 - Std. 9.800" height or 300-803 - Tall 10.200".


  • Fits OE & aftermarket Big Block Chevy engines which have OE standard or tall block deck heights. 300-802 for standard 9.800” height, 300-803 for tall 10.200” height.
  • Hilborn high-quality heat-treated aluminum valley cover castings, ceramic coated a beautiful dark gray
  • The injector manifold throttle cross-over link appropriate to the engine deck height and throttle shaft center to center distance is included in the valley cover kit
  • The machined valley cover provides two AN-10 O-ring sealed ports, these ports can be used for crankcase breathers, installation of a dry sump oil scavenge pick-up, or an oil fill location
  • The Hilborn Big Block Chevy valley covers are intended for use with a set of Hilborn EFI-R injection manifolds but these valley covers could also be used as part of a custom induction system being built.
