Also is the Holly a double pumper or not. If it has mechanical secondaries you can check to see if they open with the engine not running. Just pull the throttle back and watch to see if they open when it gets to the point the cam is set at. If it is a double pumper you will see gas squirt in the secondary end as well as the primary. And do you have the specs that tell what RPM the engine should make peak power and torque?
