MSD, can you tell the difference?

OTR, the MSD should technicaly help on the 60' times. However, since I have not run it on a car that is sub 1.7 on the 60', and have run it on a verity of cars slower, I find it a waste of money for a slow strip car. A fast strip car? Would probably bennifit from it.

I found 2+ MPG's with it on my mostly stock 360 '79 Dodge Magnum.
