I, personally, would not run anything from Accel as I've had nothing but bad luck with their coils and wires. Two Super coils that open when they got hot and Super Stock wire that had more than 1k resistance per wire. I've never run their shorty plugs, but have heard horror stories about them, I just changed to E3's in my 76 Vette, but I don't have enough run time on it to give a fair evaluation though the throttle response is good and it runs strong.
