Control your timing from the driver's seat and say goodbye to going under the hood to make small adjustments to your timing. We are removing the Msd Hei distributor and installing the 2 wire MSD billet distributor. This distributor is much smaller. You must ensure you synchronize your handheld timing with what you're reading on your timing light. Be sure to use the lock time feature during the sync process so that this process goes a lot smoother.
