What kinda plugs and for LT1 turbo? Whats up guys! Im goin turbo soon and I am unsure of what spark plugs and what plug gap to use. My compression is around 9.7:1. on a 355. I know a few people that gap their plugs at .030" using autolite 103's or something. Can I use those plugs too? If not, can anybody point me in the direction. Any help will be cool. Thanx.

I use Autolite 106 with gap .035 at 15 psi. I have an MSD coil and 6AL box.
Mine is ~8.5:1 iron heads. I tried 104's and had trouble. Each setup is different, a friend swears by TR55's. I strongly suggest you get an MSD 6AL as you increase the boost your spark will fade some where around 8 or 9 psi seems to be the trouble area for most LT1's. That of course depends on cr, meth etc
Good luck

Right now I have autolite 106's gapped at .050. I lowered my comprssion to around 9.7:1.
I'm gonna be putting the turbo on within the next few days. Should I close the gap on the autolites or should I be getting a colder plug?
