hey guys quick question. i know that your suppose to run colder plugs with a forced induction car. so what kind should i run. im a 383 on 14psi. 8 1/2 comp. thanx for the help

 

I've been using the TR6 from NGK. They work pretty good. I believe Autolite 104s will work as well. As far as gap, you should probably be around .035" depending on your ignition setup. I believe there's a gapping guide on MSD's website for blown applications, so much gap for x amount of boost.
