Not Ranked
RNT..I would think better fuel distribution to each cylinder would be the major benefit...the dual quads gave me better 2500 to 6000 rpm performance over the original 750/performer rpm manifold. The progressive linkage of front to back carbs combined with vacuum secondaries makes for good transition for non perfprmance driving.
The dual air filters are restrictive due to there size but you can still feel the improvement of the 2... 4's.
