Added the MSD setup to my 71S a couple of years ago.

1. Wiring the unit is pretty straight forward. The importance of "robust" power and ground connections to make this setup work right and last a long time cannot be overemphasized.

2. You can add the recommended ignition wires later. I used the stock wires to get everything running, then switched over to a set of Jacobs wires. Use these wires with plenty of silicone grease in the boots if you ever want to get them off the plugs!

3. I also used the stock rev-limiting rotor but soldered heavy gauge buswire across the resistor. Again, clean connections make sure you do not create a cold solder joint.

4. Getting the tach to work may was my biggest challenge. Make sure you have continuity from the engine compartment to the tach signal wire.

5. I was able to open up my plug gap to 0.040 in. with this setup.

Plenty of info and diagrams posted on this previously here. Go slow and document your changes in case you need to backtrack. Best of luck!
