After going around the horn on ignition parts mine say ACDELCO and the car just purrs like a kitta.
Experimentation is expensive and rarely yields manufacturer's claims in this area for our C4s. But being America please try them all and have fun doing it!

All a spark plug does is create an arc. Don't waste money on gimmick plugs. I've used copper core NGK TR55's and Autolite 606's in my LT1. No ignition problems whatsoever.
