AC Delco spark plug gap
I usually run NGK TR-55's gapped at .050. I was going to buy a new set of plugs, but I found a whole set of AC Delco rapidfire plugs in my pile of stuff. They are brand new, bought em a few years back and never used em. Heres a link to em http://www.autozone.com/autozone/cat...uestid=1107221
What would you guys gap these at? I was thinking .050 would be fine, but want to get a second opinion.

I agree gap them at .050 since its working for you. There should be no need to gap different then factory spec unless your running Forced induction or nitrous with colder range copper plugs.
