Ok, my friend has a hesitation we are trying to fix. I think he needs to change his plugs over already. Over the winter he ported and polished the heads and added a fairly aggressive lunati cam. He has new wires that aren't arching and an accell 300+ ignition. What would be the best plugs to run in this situation? Should that be gapped to .050 or less? Thanks.

 

95 LT1

 

Delco Rapidfires 5

 

NGK tr-55

 

 

stock gap at .050 right?

 

stock gap is correct

 

 

theres 2 version of the TR55....which should we use, the TR55GP or the regular TR55?

 

regular TR55, I think the GPs are platinums. Its up to you if you want to spend the extra $$$ on platinum plugs, I just run the regular TR55s.

 

I use Rapidfire 3's.

 

Is ANYONE using Champion?

 

I've always used Bosch single platinums with no problems


(unless you're spraying!)

 

I run champion coppers in everything I own.
