Part Two: Dyno Tuning

Rather than drop the small-block into our project truck and attempt to tune it by reading the spark plugs, we opted to transport the LS2 to Westech Performance Group in Mira Loma, California, for a dyno-tuning session. One of the many benefits of doing so is that Westech stocks a full array of BG carburetors, and our testing revealed that our initial pick of a 650-cfm Road Demon carb was a bit undersized. Westech had a 750-cfm Race Demon carb in stock, and we swapped it onto the motor to straighten out the fuel curve and improve power output across the board.
