Ah, the age old Carb vs EFI story, but this time it is the 4.8 LS Carb vs EFI and both are great options. There are a lot of ways to get air and fuel into an LS engine with all the aftermarket parts, but we all know that a factory LS truck manifold is a really good unit in the right combination. But can a high performance dual plane intake manifold, like the Edelbrock Performer RPM, do a better job with a 750 cfm Holley carburetor on top? Richard is going to show us what the truth is when it comes to comparing these two setups.
SHOULD I PUT A CARB ON MY JUNKYARD 4.8L LS? HOW MUCH POWER DOES A CARBURETED LS MAKE? CAN I RUN A CARB ON MY 4.8L? DOES A CARB MAKE MORE POWER THAN EFI ON A JUNKYARD LS? WHICH ONE MAKES MORE TORQUE, THE DUAL-PLANE, CARB INTAKE OR THE LONG-RUNNER, EFI TRUCK MANIFOLD? CHECK OUT THIS VIDEO WHERE I COMPARED THE FACTORY, LONG-RUNNER, EFI TRUCK INTAKE AND THROTTLE BODY TO A DUAL-PLANE, EDELBROCK PERFORMER RPM INTAKE AND HOLLEY 750 CARBURETOR. BOTH ARE POPULAR FOR A MUSCLECAR OR TRUCK SWAP APPLICATION, BUT WHICH ONE OFFERS THE MOST POWER ON A STOCK, JUNKYARD 4.8L?
