Title: Olds 455 Plug Gap
Post by: 75Hustler on July 17, 2012, 11:52:55 AM

Hey guys, could I get some feedback on what would be a good plug gap. I've got a stock 455 Olds with a Pro Comp Electronic dizzy. The current gap is at .035 but when I went to AutoZone for new plugs the gap is .060??

I heard when running electronic dizzy the gap should be a bit more but is .060 to much?
