Ant,
I am running the Jacobs Pro Street now. I like the rev limiter settings as you just use a jewlers screwdriver and they have the two settings in the end of the unit. One is for thousands and one for hundreds in RPMs. I think the MSD is as good in most applications, but I do get a smoother run with the Jacobs as it will vary the voltage to each cylinder depending opn the resistance of each cylinder. I am not sure that the new version of the MSD doesn't do that too. That way you will get the exact same spark and combustion in each cylinder. Example, if one cylinder has more resistance it may put 85,000 vots into it and another it may put 80,000 volts in to give the same combustion. But I would maybe try the new MSD if I were doing another car just to see how much they have improved over the ones that I had. I think both are top line and it is just a personal preference mostly. Don't use platinum plugs or any other type except the regular steel electrode with the Jacobs as they will throw the resistance readings off anf then the car will run lousy. I know, I tried it.
