glide vs, 904...bench racing

A rear gear comparison of those two would be interesting.......
There's a gentleman that runs a glide behind his 540 powered Challenger. He leaves the light like the car on the right and runs 9.60's consistently.

When her gets back to his pit, he hangs out in his trailer. Never seen him with the hood up.

I believe the glide works well behind a stroked BB, but not much else.
