This is a 540cid Big Block Chev motor will built for a customers bracket car to run on pump gas, on the dyno we used a Holley carb , but once it when in the car we changed to a Holley sniper system . By running a hydraulic roller cam , and holley sniper we made it so he had very little maintenance with setting valves and setting floats , we made this bracket car very user friendly and still made a ton of power while using pump gas. Please view , like and subscribe, we would greatly appreciate it, have a listen and enjoy, thx !!!!
