just my thoughts
I disagree totally with frank at advanced engines and the reason i do is that i have built blown big blocks and small block with alot of boost and alot of alchol and some with alittle nitro added and i have used mags and i also tryed MSD 10 plus and the 10 plus has worked great and some of the guys that are running a mag have now gone to the msd set-up and they both are very happy, i like the msd as it gives you alot more options then the mag,,, just my personal opion, we all have them.
