Better fuel/air distribution for each individual cylinder b/c the carb intake owns the LS1 style intake.

Hot Rod magazine just did a cam test in an LS motor a couple issues ago and did each cam with FI and a carb and the carb made more HP everytime.

The biggest advantage of FI to 4th gen owners, is that it fits under the cowl without modification. Carb setups were intended for conversions without space issues. For example, a 71 Chevelle that didn't want to run a Camaro ECM.
