TR6's vs TR55's
Im not planning on juice anytime soon, so my question is... What are the draw backs of running a colder plug? I mean, am i going to lose HP because of this?
One more question, ive asked sooo many people and nobody has given me a direct answer. What to gap my spark plugs to? I cant remmember the gap but i know i just guessed and left them somewhere in the middle of what everyone was telling me... Maybe, .37
Any help would be great! Thank guys!

That might be where i had them the first time around
Before i put the cam in tommorow ill check'em..
Anyone running my exact set up?
This is worse then trying to pick out a cam.... lol
Well your car is running great, but i wonder if you swaped to TR55's, would see a gain in HP and if so, how much? hum....

I am confident that these are the correct heat range to use for engines with our hp level. Too hot of a plug with high compression on the bad end of things can melt pistons. I know that seems extreme but that's the best example I can come up with. I didn't even notice a loss of hp in both of the LS1 cars I have had even when they were relatively stock by switching to the TR6s, you surely won't with your setup.

If you want the performance of copper, but much longer life, invest in the iridium plugs. Theyre the best of both worlds.

Yea ill go ahead and gap them at .45
My motor should be over 500hp & if not, then im sure its close. So i think its safe to assume this is the correct plug
I want to thank all of you for all your input, i can finally put this plug issue to rest and worry about other things like, where the heck to buy my catch can and my msd wires hehe

I recommend the AMW catch can, they raised the price since I bought mine but it is a high quality piece no doubt.
Got my MSDs at Thunder maybe???? Been to long lol, just the cheapest sponsor, but that's a given.
