Ant ... good plan on using testing the motor with the mufflers you`ll be using . It made a significant difference on my carb setup as my engine was dynoed without mufflers and , obviously , I have mufflers and also merged collectors . Carb ran rich at light cruise and low rpm ( 2200 to 2700 ) with the on car exhaust system vs dyno .
Have fun !!
