I am wondering what is the best gears to run on a 1/8 mile track? Either 3.73 or 4.10? I dont really know what is the best RPM to be at but if you can give me help, I'd appreciate it. Thanks.

What is the ratio of the gear your running in your tranny. A 1/8 is a pretty small track and to be honest with ya I wouldn't know what gear to run. I run a 1/4 mile track with a 3.90 and the tranny in 2nd (1.68) which gives me a 6.55 final drive but I'm going to run a set of 4.10's to get my RPM's up. I would think that on a track that small your final drive should be a minimum of 6.90-7.00. Sorry I couldn't help ya more

It might be almost a 1/4 of a mile, but I dont really know exactly but I talked to the guy who runs the track and he said that it was a little longer than a 1/8 of a mile. If you can give me help with the RPM's and what you really want them to be Id realy appreciate it.

How stong is your bottom end? What is the rollout of your tires? If you have a stock bottom end I would at least get your final drive in the 6.90-7.00 range. If you feel you can go more than that then I would try it. But, the rollout of your tires can also dictate how many RPM's you pull.

Your rpms are totally dependant on the quality of motor you have. I like to keep mine around 5,800 but i have to run a totally stock motor. I also dont have alot of money to put in top quality parts. In the tool box is a great gear selector equator. Check it out and see what tranny gear you have and then decide what rpms you want and it will give you the gear you need to achieve it. You also need to know the tire size too in order to get it right. Good luck...
