Default what plugs with LT1 w/ vortech

Currently there's autolite double platinum app 606's in there. I though supercharged apps weren't supposed to use platinum plugs. Also, what gap are you guys running?

I have a full ignition system on the car. The gap is approx .58 right now. That doesn't seem right to me. Heck, on my blown mustang I run approx .30 gap or half of what I'm at with these.

No wonder the car isn't running right...

I've run Autolite 104's at .040 with good results.

Had wicked misfires at .050, I can't beleive your car actually runs under boost at .058...
