LS MARINE ENGINE CONVERSION: GM LS 4.8, 5.3, 6.0, 6.2 Installing the Carburetor


This week we install the 650 CFM Quick Fuel Carburetor on our LS motor. We had many questions on why we chose to use a carburetor rather than EFI. We did so for a couple reasons. 1), its more cost effective and 2) we don’t have to run an O2 sensor. We’re using a 1″ carb spacer and 1″ extended length mounting studs with our application.
