spark plug gap
 

hey guys whats the plug gap for an ls1 thanks in advance.

I did mine at .55 with NGK-IX Iridium spark plugs and the Red GM Z06 or LS6 Wires.
But i know it says .60 for stock but alot of people go between .50 - .60 depending on preference i guess but i just went with what my friends that have LS-1's set theirs since they said it worked good

ive heard .50...but im not sure.

depends what plugs ur gona run

the acdelcos iridiums are pregapped so u dont need to touch em, denso's are the same way and ran good in my car the NGK tr-55's i tried gapped at .055 and they ran ok but when i pulled them they had more black on them than the iridiums did after who knows how long.

Yeah, I got the service manuals for 2001 recently and they indicate the gap at .060 for the 5.7L. Not sure what it is for the V6, but who cares.
