Re: No Spark coming to plugs
ALWAYS, large gauge ground wire from negative BATTERY term, directly to engine. Our cars sometimes have an accessory small gauge ground from BATTERY to front sheet metal. then, added ground straps, engine to chassis/body.
As far as the Blaster 2 coils, they are notorious for being defective new, and/or causing ignition module failures for both MSD boxes, and HEI systems. Plug gap with one of those coils, NO MORE THAN .035.
