Kaps, "hitting the rev limiter before the finish line" is pretty normal at your age. Biggs has some little blue pills that he says get the job done--he may share some for an old timer like yourself.

Don't forget the other factor involved in the equation--tire height. That's how 1Tony ran 144 with 3.55's; he used a 28" tire and went through the traps right at 6100 rpm I think.

RedGTS has a good point. You can go with the 28 inch tire and have a few mph to spare.

155.09 - You get a lot of potential MPH from the extra size. The trade off is getting the car to 60 foot without bogging the shit out of it.

Here is a link the calculator if you wanna run some numbers. A 3.07 with that tall tire could turn 168mph at 6200rpm! I think it will be awhile before we see a viper running that speed at the drag strip.

I have hit 146.8 with 3.33 and 26' tires. The shift light was on but did not hit the limiter. Don't forget that even a 26'tall tire grows by the time you hit the traps. M/T has the tire height at 26.2, when mounted on a rim.
