MSD retard box.

[ladybird]

I am gonna put a a 150 shot on my 96 LT1. I am looking for an ignition box made by MSD that will work with my car that has some type of builtin nitrous retard. I was told that it is wise to take 5 degrees out when the nitrous hits and I want to run a box like the 6AL, but I need the built in retard feature. Any suggestions. Thanks.

An inexpensive easy way to add timing retard to a 6a or 6al box is MSD's #8982, they use pills to set how many degrees to pull. Simple to hook up and work well.
