These threads are always interesting.. Some look to make more power. Some want to do it with gear, tire and converter..

Personally, I prefer making more power. You'll throw over $2,000 at tires, gear and converter, and it will still be a power weakling. All that tire, gear and converter gets you is a better 60ft, For me I'd rather have, and find more fun, a 12.8 car that runs 110 mph, verses a 12.8 car that run 104 mph.

Also, I highly doubt that you'll be able to 60 ft your way to a 12 sec et with a street car that has a 100 mph trap speed.

With a good head, 10:1 cr, and a 230° cam, you should be able to run 108 mph in a 383 Dart.

What is the race weight, and what was your race day DA?
