Extensively modified, stock-appearing carb that produces the most HP possible utilizing a stock carb body. No external epoxy

In addition to having the largest Venturi area of any of our other bored carbs, the butterfly size has been significantly increased to provide 60% more airflow than a stock carb. Fuel circuits and jets have been reworked to maintain proper mixture. Choke is removed.

Venturi is CNC milled and is oval shaped to maximize volume and velocity. Equivalent bore size (area) is greater than a .670" bore

Stage 3 carbs have no epoxy on them, however they flow same as the stage 2 carbs.

Dyno testing shows these carbs to produce up to 1hp more than a standard bored (stock butterfly) carb, and over 2hp more than a stock carb with only marginal loss in low-end and idle quality.
