The combination of the BLP carb and the MSD ready to run distributor make tuning a lot easier. The BLP carb has fully jetted metering blocks so we can quickly dial it in. The MSD lets you change the advance curve by just turning a screwdriver. I just changed from 15 initial and 20 in the distributor to 20 initial and 15 in the distributor. Took less than 90 seconds to do that. With an old MP distributor you would be there half the day taking the thing apart and welding up the slots.
