massive reconfiguration time again.
I wonder how much it was the cam change and the rings sealing?
4 years of Spirited driving and drag racing usually doesn't provide better combustion numbers LOL
I'm pretty sure I found out why I have to put a little bit of race gas in it...
I cross referenced my usual Autolite ar3934 with the NGK V power 4554's and going to try those and see how they do. (.040 gap) Only 20 bucks for a set their much cheaper and look the same...
