For what? Driving to the store? 2-hour endurance race? If it sparks and fires the mixture when it's supposed to, there's no need to change anything. Don't fall for the hype.can someone advise, e.g about MSD? Is it worth investing $200 extra to digital box for something that analog 6AL cannot do?
Look up the spec sheets for both MSD boxes. The digital is more likely to have extra features, since its easy to program functions into a digital processor.
As far as digital electrical signals vs analog electrical signals, there shouldn't be much difference. At 6000RPM, each cylinder is firing 100 times a second. Both types of circuits are going to be able to work at that speed. Milliseconds (0.001 sec) and even microseconds (0.000001sec) are plenty of time for the electronics.
The digital ignition might be able to prevent over-reving. Ive also seen some with a feature that detects driveline failure and stops the spark before it over-revs. The analog box is a straight-forward box that increases the energy in the coil, will multiply the sparks and can still kill spark when it reaches the limit.
I have a 6A and blaster2. It starts up so much easier than the stock setup. Would I notice the difference of a digital ignition? I doubt it. I dont race it down the track at 200mph.
But dont let people tell you that digital electronics are faster or better than analog electronics. Theres a lot of marketing out there that make it seem like something is better if its digital. Sometime it seems like people associate 'analog' with 'vacuum tube' or 'low tech'. I work on analog processors that operate at 60GHz, and are not low-tech by any standard. Digital circuits cant process information fast enough for my applications, but they may work better for other applications. It all depends on the application and design. and its hard to compare how one works inside vs the other because the information of 'how it works' is not released to the public. The spec sheet and tech support are your best bets.
I say you get the 6AL, then spend the remaining $200 on gas to drive somewhere fun.

yeah, i guess i forgot about those two extra exhaust stokes.
PAZUR: since it sounds like you dont know whether or not to spend $200 on the fancy version, you're probably like me and cant buy every shiny thing at the parts store. if my assumption is true, then there are probably other parts on your car that need attention, i would say some of those other things are probably more important than a digital ignition.
