What is the best set up for an MSD system when changing from a points to Electronic? I am planning on adding the factory Tach. Does the Tach adapter work well? I have a 69 Camaro.

Steve,
If you go with MSD make sure it will fit. Most wont and you end up dimpling your firewall to make it fit. There are small body MSDs out there that do fit. I went with the pertronix. You remove the guts (points & condenser) from your existing Distributor and put in pertronix "Stuff".

I believe MSD makes 2 different distributors. There is a small cap ready-to-run that you can use with or without the MSD 6AL box. Also there is the large cap HEI. To get them to fit I believe you have to change motor mounts and towers. I believe they are the BB ones. But do a search first. I wish I had known this ahead of time as I dimpled my firewall to get it to fit. But it works great and I added the factory tach to my non factory tach car. I did not need any tach adapter. Mine is also a 69.

Ted,

Everyone says the factory Tach will not work with an Electronic ignition due to how it recieves the voltage. How did you wire yours?

I installed the Crane xr-1 conversion & An MSD box in my Camaro. The tach works without any modification. It also has a rev limiter built in. Works well.

I think you are right, a true factory tach does not work unless you get some sort of adapter or something. I think I have read that in other posts. But the newer ones that you can buy on ebay or parts houses will work. Mine works fine no issues. If I remember right there are 3 connections key power, ground and then the wire from the HEI tach to get the signal. Check on tach wiring install or something along that line instead of me trying to remember. That was a whole year ago (oldtimers desease). If you are going to install a tach in a non tach car it can be done without taking out the carrier. I did it in my 69. I might even have an extra template all ready printed out. There are tach templates in some of the posts. But just remember if you use them and are leaving the carrier in the car. You have to make a mirror image of them. The most important thing in cutting out the template is not the design of the tach body (since no one will see it), but the tach mounting hole location.
