More Tracks R Going 1/8 How to gear a low HP Car??

I, too, avoid the nine second threshold.
I have two tracks near my house, twenty miles in opposite directions, one 1/8, one 1/4. (I personally prefer the 1/8 track, but thats neither here nor there.)
My small block car, i started with 5.14s in a nine, because of 14x32 tires. It seemed a little much, so i changed to 4.71, and the car slowed down......nothing. I can run either track.
My big block car has had 4.56, 4.11, currently using 3.91s. It doesnt care what gear is in it. I also learned it runs just as fast shifted at 5900 as it does at 6400. I am in high gear by about 400 feet.
My new big block car is going out at first with 3.50s for the eighth, we will see how that works. 4.10s might be the first change.
I guess what i am trying to say, is..... i am not really impressed with success with very low gears.
