Yep, that's what I had been running when I had the LS1 in the car with a NOS125 shot...they are a step colder for nitrous right....
But I was wondering with all this air flow if the TR6's were getting "blown" out...I was getting some stumbling on tip-in below 3500 rpm. I know...Maybe nothing to do with plugs - probably just reversion from the cam/lift.
Just want to make sure everything is really right this time around. (rebuilding the oil smoking 402 to a clean 408)
Putting a GS vac pump on it too this time!
Thanks, Ram.

I do want a decent idle and less stumbling with tip-in throttle down low. Maybe race plugs are going in the wrong direction for me.
Maybe with the vac pump, less blow-by and better tune this time, I'll have a better streetable driver.
I may not even spray it, (492 hp NA at the tires not too shabby as is)... I do need this engine to last! Appriciate your help!
Any one else have advice on best " N/A or mild shot of spray" plugs for my 408? Gap?
