Default Re: 72 TA : New Project

Looks like those plugs are running a little hot. Considering this is just from "normal" driving, the heat line looks like it is pretty far past the bend on the ground electrode, and are there tiny little black specs on the porcelain?

What heat range are they?

Compression ratio?

Where's the timing at, and have you heard any audible signs of detonation? (Sorry for all the questions, but Pontiacs are known to be finicky about their tune)
