Which plugs are best for the LT1
A LOT of guys who really know what they are doing lack the stuborness to argue with the average poster here so they don't post, and a LOT of kids with basically stock cars think they know all there is to know about heads/cam/shortblocks. Agreed post count means little.
I think signatures on the otherhand can be telling, some guys have monster builds details but then no track info or mediocre results listed, some guys just have almost nothing listed and some guiys have combos that clearly run well for what is listed. Choose which one of those you listen too carefully.

I have less than 160 posts so I probally dont know what I am talking about but I have used the Ngk Tr55 they work out alright I am going to switch to the Tr6 because my compression is pretty high now. But They seme like a good plug . Havent tried the autolites in lt1's. But when my car was just a bolt on car I liked the factory AC delco platinum plugs.
Im using the TR-55's platinums and they're holding up a lot better than the regular ones. I fouled em out in a matter of minutes, Im getting new ones today though cuz the cars been down for a long time.

i am running just the plain old bosch platinums, and they have seemed to run fine for as long as they have been on the car.... next change though i will prob. be running the NGK's
Bosch +4 SUCK.....I had them in my car for maybe two weeks and switched to NGK. My car never ran right with the Bosch...I also replaced the Bosch 02s, what a waste of money. Replacing LT1 plugs twice in one month was a real pain in the ***, my hands looked like they had gone through a war!!!!
AC delco platinums (LT4 plugs) were good for my NA setup but i just fouled some since it sat for 9 months and tried to fire it back up but im either going with autolite or else NGK
Stock delco's are the best for stock to slightly modded lt-1's. Ngk tr-55 is best for modded na lt-1's. No experience with autolite's but hear they work well. Don't buy into those high dollar gimic plugs such as E3, splitfire, and denso. They are a complete waste of money!!!

I either put AL605's or 106's in mine, can't remember which. I've ran NGK in the past, different car, TR6 and TR55's. Good plugs. Can't go wrong if you can get them cheap, but not worth a 5 dollar price tag some places have them at. I stay away from AC's like the plague. Love their plug wires, hate their plugs.
I'm running NGK TR55's with no probs. Second set due to the first set having those retarded *** twist off tops. Second set have the solid tops. I've just got a bolt-on car besides impala headgaskets to bring my compression ratio up.
