That's about "entry level"today! I'm running that on my 6 cylinder! Even if you made it 170 or 180 it would help!

Its nice to day dream and BS about it but what does it take to get it done? I dont have any "pull" anymore and NHRA wont listen to anyone or their own committie so what can you do? Build your combo with the lower valve spring pressures to make it less expensive, get more runs and run slower or just keep on spending the big bucks for the trick of the week, rebuilding them every 75 to 100 runs and/or blowing up very expensive engines I guess.

Take away an engines ability to rev and it will be less likely to hurt itself. NHRA is looking for ways to cut down on "down time" so it would seem to just be a common sense rule. BUT I did say NHRA and common sense in the same sentence didn't I? Isn't that like saying Military Intelligence?
