Not Ranked
i have had two PRO SYSTEMS customized 780 holley's built , they do a great job. all i had to do was adjust the idle , otherwise right out of the box it was right on. and when the car was chassis dyno tuned, the air fuel ratio and jetting for the carbs did NOT have to be touched. it was perfecto. bill
