Default Thoughts on NGK

Well I put the NGK TR7's on yesterday. Seriously, it gets easier every time you do it.
I've elected to try a .35 gap this time around. The old plugs were set at .50 no wonder I was getting blowout since I only have an MSD coil.
Car seems to be the same, only maybe a tad on the rich side. could be my imagination, I will be taking a log tonight to confirm my suspicions. Other than that, the rpm response seems to be identical right until 5500 when it builds much better than it did before. For those who were following my "oil pressure loss" thread in tech, the problem hasn't occured since the plug change, though I'm going out of my mind to deciede if that is at all related(my gut feeling says no). Thanks for the advice MOJO. Now it's time for a little racin'!

Cool beans, the smaller gap will help a lot... as well as pulling some fuel... just watch your knock.. are you intercooled?

Yes I have the ATI 2-core air to air intercooler (old one peice style). It works very well (IATs in the 145-155 range in 90 degree heat after full warm-up).
