Ignition experts help an LT1 guy out.
Ignition experts help an LT1 guy out. Ok, I don't know how many LT1 guys are in here but I figured this would be a good place to ask. As I discovered today, MSD is offering a complete Opti-Spark replacement with all kinds of fancy improvements. Before I had heard this, I was considering a Delteq Opti-Direct system, which uses brand new coilpacks designed for the V8s in Auroras (and Northstars as well if I remember correctly) instead of the single-coil system in the stock Opti system. The optical sensing unit of the stock distributer is still used, but high-voltage is no longer in the Opti to cause internal cap & rotor wear, internal arc over, and cross firing trouble. The supposed advantage of the multi-coil setup is the longer charging time for a more powerfull spark. There are several companies that manufacture an "improved" opti, now MSD as well, so I'm wondering, is there really any advantage to the multi-coil setup? Because honestly the MSD is more attractive to me due to an easier installation. Any help is appreciated. Thanks!

The only advantage is the one your stating about crossfire trouble and cracked caps etc., no more opti troubles. Other than that,the coil packs are just a trick of the week part that look cool and cost money (the LS1 has them so I need them). The MSD stuff in the past has been very good stuff some I'm sure you would not be disappointed in the product. The truth is if you don't have a major ignition problem there is no real gain in new ignition like some manufactures claim.
