I assume dirt oval racing, most track sizes get over estimated but if indeed it's that big, I'd start on a 22/62 but it's really hard to say as available grip plays a big part, I would have a 20, 21, 23, front driver with me and 56 to 66 rear gears as well, biggest track we've ran the predator is a true 1/5 th mile with real good grip and it's a 20 front driver.

There's so much to consider! 1st, the track layout. Tight turns with long straights, big turns with short straights.
One tooth on the driver is equal to 3 teeth on the axle in the ranges that have been recommended.
RPM, what is the peak RPM you can expect to see on that track? With what gear ratio?

First is this dirt oval racing ?
When you say small track, what size would you guess ?
An 11 / 67 on a red plate , I would think that was a gear rule not by choice ?
 
No by choice it’s a very small track this past weekend we went up to a12/70 was a lil better but was lil slow coming out the corners

For that gearing to be even in the ball park it better be very small, like racing around your garage small, pull about 6 off the rear and test.
