I take it you are running 1/8. If so do one or the other but not both. Select rear ratio based on rpm crossing finish line. For 1/8 I'd do glide and current gears for 1/4 keep current trans and regear

I went from the 4l60e with 355's to a glide with 180 straight cut gears and still 3:55's, just have to make some suspension changes as its not recovering from the hit as well.
what some forget is the ratio of gearing. 4l60e has 3.06 1st so with my glide I would need 5:38's at least to have the same 1st gear pull lol that's why off an idle my 4l60e would do mid 130's all day.
what happens is when you don't have a lot of 1st gear when the tires spin they have a hard time recovering due to not matching the speed of the car trying to accelerate. A lot of gear, the tires have a good chance of recovering as they spin they are matching car speed easier.
hard to grasp concept but in all the NHRA events with the pro classes they talk about this in detail.
the reason I say this is with the 4l60E I would hit 200 to 300 out of the hole and go and if I did spin it would recover looking at my 330 times. So I stepped it up to a glide and thought it would work better right out of the box but now it even spins on a 150 hit when it never did before. so just some adjustments to iron out. hope it makes sense lol

Lol, no offense taken at all. I know sometimes we write something and it comes out sounding wrong. I've done it a few times not meaning how it came out.
