Grudge match HELP!

You're getting a lot of good information.

I agree with stroked 340, anybody can add nitrous, and knowing the power range of your cam for shifting, and the tire and gear combination for the 1/8 th mile has to be right, for some basics.

What size tire are you using ? I don't think it was mentioned.

Beautiful car, from the picture it's hard to tell the true color.
When you change wheels the other guy will know what you did, but so what. I think you need to Catch up and use some street slicks, and when he sees that, it will put the pressure on him.

But we need to know diameter tire you're running now.
What's your trap speed and RPM ?
