There are an insane number of intake manifolds available for LS engines, but the most common are for fuel injection systems since that is what they came with from the factory. Conversely, the number of intake manifolds available for a small-block Chevrolet favor the carburetor setup more than EFI. But just because an engine came with a carb from the factory doesn’t mean it can’t have fuel injection installed, and just because an LS engine came with EFI doesn’t mean you can’t bolt a carburetor on one and have it work great. I know, it seems weird, but it is true.
But which intake is best? Single plane? Dual plane? How about the trick Holley two-piece intakes?
Richard has the answers.
Video Description:
WHICH ONE MAKES MORE POWER, A SINGLE PLANE OR DUAL-PLANE INTAKE? WHICH INTAKE MAKES MORE TORQUE? WHICH INTAKE IS BETTER FOR A STREET/STRIP APPLICATION? DOES A 4.8L NEED A DIFFERENT INTAKE THAN A 5.3L OR 6.0L? HOW WELL DOES THE HOLLEY 2-PIECE, SINGLE-PLANE INTAKE WORK? IS A HIGH-RISE INTAKE BETTER? CAN I RUN A CARBURETOR ON AN LS MOTOR? HOW WELL DOES A CARBURETOR WORK ON AN LS MOTOR. WHAT IS BETTER, CARB OR EFI? CHECK OUT THIS VIDEO WHERE I COMPARED THE 2-PIECE, SINGLE-PLANE, HOLLEY INTAKE TO A DUAL-PLANE ON A CAMMED AND MODIFIED 5.3L. I ALSO COMPARED SINGLE AND DUAL-PLANE INTAKES ON 2 DIFFERENT 4.8L COMBOS!
