If your distributor isn't locked out change the curve on it like all in at 4800 or what ever max curve you can get out of it. Also have the centrifugal advance timing set to the max. Like with the MSD you can have it setup for 28 degrees so if you wanted 36 total you would set base timing at 8 it will run bad and very sluggish when you tip into the throttle. At that setting you may have to leave on the second yellow.
