Any reason NOT to run Autolite spark plugs?
I've always had good luck with Autolites, but I see darn near everyone says to use NGK TR55's. So far, I'm not having much luck finding them though. Aside from "because everyone else uses them", is there a true gain to be had in using the NGK over an Autolite spark plug? Not concerned about a money difference, but I would like to be able to go to the parts store that's a half mile away and get plugs if the need arises after this plug change.
I'm close to doing my longtube header install and it will surely be the best time to do a plug swap, I'm assuming.

Spark Plug are a subjective subject.. many time it is mind over matter that it is a better plug.
You can either go wtih everyone else and if that work and for many it will..
Else you can just what you have alway used for year and if that work.. keep using them.
or you can keep trying other ones until you find something that you think give optimum performance.
Right not I am using the stock AC's and they seem to be good and no problem. for my other SBC.. i use Champions and have always had good luck with them.
so.. make up your on decision based on real fact and what works for you.

Alright guys...NGK TR55's it is....The car had Denso's in it, so I guess they have been changed sometime before I bought it.
I know one thing...I installed my JetHots this afternoon/evening and these LS1's in Fbodies don't give you no kind of room to work with...lol. However, The beer does taste very good this evening though...

But you can't go wrong with proven performance and durability.

Mine also had densos in it. I guess GM was using them for some time because of supplier problem. From the looks of my denso's im thinking they were the wrong heat range because they were really burned up. I went with the copper NGK TR55's. Pulled a plug a week after install, perfect grey color.
