I think the penalties are just to keep most on a semi-even playing field so everyone can compete. I mean, I could have a .474 lift cam in my Duster, but instead I have a .427 lift cam and get the same penalty. I ran this race 2 years ago with 2.45 gears, but could have had 2.94's with no penalty. But, the top cars have always been within a tenth or two either way, some exceeding and some almost running the number. Last year I was 2nd and exceeded my number by the same as 1st place, but the tie went to the faster car
