Hum. I suppose the reason that you are going with this FI setup is that you got a deal on it and not that you want it to look period correct for the car?
Period correct look would be with a distributor.
I personally am going with the distributor. I'm using the Duraspark with a small cap so it fits.
The GM style cap with the built in coil is a nice idea but only a small cap will fit.
It is also a proven setup as far as durability and one is not reinventing the wheel with it.
Of course if you plan on turning this thing like it is a Formula 1 car at 11 or 12,000 rpm, then distributorless is the way to go. It will make one less component that you need to put back in the car when you blow this one up.
