Go with what the General recommends. You would not believe the testing that goes into spark plugs. If there was a better plug they would have used it on the assembly line. You stock ignition will only supply so much spark. Don't let the aftermarket gimmick plug become a source for electrical resistance. By the way, Accel plugs are made on the same equipment that churns out Autolite plugs for $1.49 ea. The individual packaging constitutes for @ 18 cents of the plug cost.
Stick with AC plugs for your Chevy.
