Holley EFI is excited to launch four new multi-point fuel injection intake manifolds for the big block Chevy. These new intakes are available to fit oval or rectangular port heads, and 4150 or 4500 style throttle bodies. These Intakes are ideal for converting your big block high performance or racing engine from carburetion to fuel injection. These intake manifolds were computer designed and dyno proven to produce more horse power and torque than other EFI manifolds. Each manifold package includes anodized and laser etched fuel rails, and two sets of mounting brackets (brackets allow use of 1.48" or 2.56" O-ring to O-ring injector lengths).
 
Features:
  • Open plenum/single plane design
  • No EGR provisions
  • 3500-8000 RPM power band
  • 4500 carburetor mounting flange
  • Includes fuel rails and mounting brackets
  • Designed for today's larger cubic inch big block Chevy race engines
  • Perfect for hard core drag racers in the NHRA Super Comp, Super Gas, and Street classes as well as IHRA Quick Rod, Super Rod, and Hot Rod categories
  • Rectangle Port Dimensions: 2.28” High x 1.48” Wide
  • Height: Front 5.96", Rear 5.96"
