some don't care about not seeing it. and with a stock air cleaner on the car i doubt you would see it either without pulling the air cleaner.
i've used pertronix in the past. worked very well. only problem is if it fails far from home you are kinda screwed unless you have a points set up sitting in the glovebox or something.. not getting a replacement at the local parts store.. exactly why i like the HEI module. just about anywhere sells those things if you need one.
