I read on here a couple day ago that by putting on a MSD box it retards your timing like 4 degrees right off the get go ... is this true?

That may have been me to make that statement. I should have clarified and said that I've read that the MSD "spark retard" boxes have been shown to include some mandatory (unwanted) spark retard.

I don't think their standard ignition (i.e. 6, 6AL, etc.) affect anything with timing.

Sorry for the confusion.

It has an adjustable start retard on some boxes, but ive never read that it retarded base timing for regular driving.
