I have my rig in the shop it getting needed adjustments . valves, fuel pump timing, replace the fuel lines. They put it on the Dyno and it squeeled at 276HP. They suggested I put a cam plate in and said they could get it up to 326 HP . I have a heavy duty Southbend Con clutch. Well Iam confused. It has a #6 fuel plate now. Is the cam plate something different they want to install. I dont understand. Please explain
