the cylinders did, but fired the plugs out side the hole and they all fired, just weak ,white spark. when I tried the new plug, it was bright blue, like a welder

 

lol i see what u did there, bravo

 

That's awesome.

What plugs were in there before?

 

factory auto lites ht1

 

auto lite plugs werent factory, motorcraft plugs were, but the autolites were prolly installed at the time the vortech was

 

your right, motorcraft. the speed shop that dyno tuned it said they should have been changed when they installed the vorteck and changed the injectors, but he strongly suggested changing them now to the colder range

 

correct it is mandatory to change plugs to at least 1 range cooler when going forced induction
