To change the timing curves, simply remove the distributor cap and rotor to gain access to the bushings and springs. The idea is to achieve as much initial advance as possible without dragging the starter, and to reach full total advance by 2,500 rpm.
Installing new ignition components isn't too tough for a mechanic or enthusiast with average mechanical skills, but if you're unsure about the job, we suggest thoroughly reading MSD's detailed instructions before you get started. We've done this kind of work before and had all our MSD components installed in less than a day, but taken at a more leisurely pace, we'd consider the job an easy weekend project. Though we didn't see a huge improvement at the dragstrip, our elapsed times did improve. More noticeably, the car starts instantly, runs smoother, and revs freely, making it even more fun to drive. Most importantly, if a drivetrain component ever breaks, or in the unlikely event we ever miss a shift, the engine will be protected by the built-in rev limiter.
Before removing the old distributor,...
Before removing the old distributor, mark the number-one spark plug, then pull the cap and verify the orientation of the rotor. The new distributor should be oriented the same as the old one.
The MSD distributor slides...
The MSD distributor slides right in place of the original unit. By holding the housing and rotating the rotor, you'll feel the distributor gear mesh with the cam gear, and the distributor will drop into place.

The 6AL-2 offers digital circuitry, and the two stages of rev limiting are easily adjusted through the holes in the ignition housing. A small screwdriver is included with the ignition for this purpose. The LED light on the side lets you know the unit is working properly.

In addition to the detailed instructions, the wiring diagram for the unit is also embossed on the back. The wiring is very simple, almost as easy as wiring one of Editor Heath's guitar amplifiers.
The ignition unit should be...
The ignition unit should be mounted away from heat, and in an area that won't be exposed to the elements. After considering our options, we chose the back of the left (driver side) inner fender. Using the unit as a template, we drilled four holes and installed the rubber isolators provided with the ignition.
