sst1226 - I've 1/8" mile bracket raced for several years and I've seen several of my buddies over the years swap from a TH350 to a Glide and anyone who did instantly picked up .15 just in the 1/8" mile with a Glide.
There is less rotating mass with a Glide than a Turbo. Most anyone who has gone quicker with a basic Turbo versus a Glide has had the wrong converter / differential gear ratio in their car to start with.
Good luck with your car.
