If you glide guys only care about consistency, and not making the car quick, why not just build a /6 dart with a 904...

Come on... we're drag racers.

And to be honest, a lot of cars that run glides run superpro anyway, which allows delay boxes and air shifters. So hitting the shift RPM is kind of a moot point for most of those cars.

I'm not saying it doesn't have it's place, and there is NO QUESTION that they are cheaper, but it doesn't mean it's always the best choice.
