Spec 3

These carburetors are built to a track and dyno proven design. They feature a special venturi and booster combination that provides unmatched power and throttle response, fully adjustable metering blocks, thinned shafts, stainless or plated hardware for corrosion resistance, HP body, alcohol jets, and custom calibration. These are super smooth, responsive, and make excellent power. They are a great fit for IMCA & UMP modifieds, or late models with up to 410 C.I. motors.
