300-132 Mid-Rise Single Plane Carbureted Intake for Cathedral Port LS
Bolt a 4-barrel carburetor onto your cathedral-port LS. The 300-132 is a mid-rise, single-plane intake for GM Gen III/IV LS1, LS2 and LS6 engines, with an O-ring cylinder-head flange for an OEM-style seal and simple installation. Built for street/strip and race use from about 2,500 to 7,000 RPM.
- Mid-rise single-plane design, 4.95 in. height
- 4150-style square-bore carburetor flange
- O-ring cylinder-head sealing flange
- Operating range: approx. 2,500–7,000 RPM

- Backed by us. 30-day free returns and a 1-year warranty on casting defects.
Frequently Asked Questions
Will it fit my LS3 or 5.3L truck engine?
It depends on the heads. It fits cathedral-port heads only (many 4.8L/5.3L/6.0L truck engines use them). It will not fit rectangle-port heads such as LS3 or L92.
What else do I need to run a carburetor on an LS?
A carburetor-compatible fuel system (pump and regulator) and a standalone LS ignition controller, since the factory ECU won’t run a carbureted setup.
