Bench racing "mine vs yours" will lead to nothing more than into a never ending no winner arguement.

Regardless of ones tuning abilities the bottom line is that the results of a head to head comparison between a good 4 barrel/intake combo vs. a well tuned Six Pack combo will vary with nearly every engine/car combo, both have their merits.

It's safe to say that any advantage will be marginally small in either direction (speaking street/pump gas setups here) it's all about the fuel requirements of any particular engine and what one is willing to spend (time/money) experimenting trying to ring out every last HP possible from their particular combo.
