Info

This is Garage Sale priced because it is an open box item, it has been bolted up.

Got an LS engine to get running? Nothing is easier than bolting on a carburetor. Holley's dual plane carbureted intake for GM's LS engines will help you get on the streets quick! Its dual plane design makes it perfect for low end torque, yet it still pulls all the way to 6,500 RPM! Our O-ring cylinder head mounting flange gaskets provide an OEM style seal and make installation a snap. Bolt one on today!

  • 4150 square bore carb mounting flange
  • Optimized runner layout and constant cross sectional area provide a broad torque curve
