Spark plug question I am wondering which spark plugs to use on a built 350 LT1 with ported AFR heads. The spark plugs on the engine are autolite 3924. Should I buy the same spark plugs that are on the engine or would there be better ones to use.

From what I can gather the Autolite 3924 is slightly colder than the 104, judging by info on Autolite's website.
I'd say colder is better especially if you are going to tune more aggressively.
