4500 Big Dual

While sitting on a standard 4500 bolt pattern, the 4500 Big Dual offers a massive 25.8 square inches of throttle area, making it nearly twice the size of most four-barrel 4500 carburetors and throttle bodies.   With four integrated fuel injector bosses and optional injector spacers available to allow an additional eight fuel injectors, the 4500 Big Dual is as versatile as it is innovative. 

Includes two fuel rails and stands.  Fuel injectors not included.
