There is a high end auto repair shop in Gardnerville, NV (near where I live) and they have a Sun Distributor machine. I have just recently had them convert both of the distributors in my '69 RS and my '66 Chevelle to electronic and eliminated the points by using the Pertronix kit and the proper coil to go with the new electronics. Distributors were dialed in and curved on the Sun machine. The Pertronix conversion (as well as similar offerings previously discussed in other posts in this forum) allows you to use the original distributor housing. In my opinion, this is a much better way to go in that you don't have to "beat to fit, paint to match" like you will have to do if you go with the HEI unit. The coil should also be upgraded and if you really want to add the finishing touch, don't forget about the spark plug wires and the plugs themselves. The new electronnics will support platinum plugs if you want to pay the additional cost.
Also suggest that you read JohnZ's discussion in the previous post below:http://www.camaros.org/forum/index.php?topic=64.0
