carb or efi

Cab with wideband 02 in the exhuast. You can dial in your A/f for wide open throttle (12.5 area) square jetted with a power valve block off installed. You can then lean tune for the street if you want by finding the primary jet that gives a good cruise A/F (like mid 14s) and then increase the power valve restrictor channel size back up to square jet size with the power valve.

Also with the carb you get the fuel cooling from the venturi velocity increase. Good for power.
