Spec 3

These carburetors are based on the 80496 950 HP with reworked fuel curve, main body, and base plate for better throttle response and more power. These carburetors have great potential from Holley and we make the changes to maximize this. They feature stainless or plated parts for corrosion resistance, alcohol jets, thinned shafts, custom matched venturi & booster combination. These are a great fit for IMCA & UMP modifieds, or late models with up to 410 C.I. motors.
