Default Re: Starting line ratio for manual transmission application

I am assuming the original poster must have a low gear ratio of 2.76, which is quite tall for a drag car, especially as it looks like he has a fairly big tire on there. Going to 5.57s should increase his trap RPM around 600 RPM, but I would also be looking for a lower first gear in the transmission. What the current 60 foot and 330 numbers, and what size tires on the car would be helpful.
