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.
