3400/3.4 spark plugs

[FireShadow]

I am edging towards complete with my 3400 build in my Camaro. Soon I will be doing a 100 shot of nitrous. Does anyone know which sparkplugs I use on the 3400 heads? A while back I picked up some ngk tr-55 iridium plugs but I would like some second and third opinions. Thanks guys.

Thanks, just wanted to make sure what would fit in the 3400 heads.

Make sure they are the ones for the 3400 heads. The Camaro plugs will be too far up in the spark plug thread/bore. Camaro (iron head) plugs are .460" and the 3400 plugs are .708".

So are there different application TR6's? When I looked into this a while back the best I could come up with were TR55's for the 3400 heads but those aren't really going to be good for nitrous according to my teacher. Sorry, as some clarification it is the Iridium IX TR55's that I have.
