Power glide on the street?

Power glide on the street? I'm thinking about swapping my 4L80E for a glide or a TH400. I had a 400 in this car before and it worked the same as the 80 from a racing stand point except for the additional power it eats. I'm looking for some feelings for those of you running a glide on the street. I'm well aware of the drivability differences as Ive had glides in street cars before but they were daily drivers that I didn't care too or try to race. I'm curious as to what your cars weigh, RWHP, rear gear & tire height are and how well it leaves on the street. I don't see the track much and I currently have my car setup to work best on the street. I know I can leave @ the track off a t-brake with the gas @ 4Kplus and a glide will be fine but on the street w/ a 3350lb car, 600FWHP N/A, 28" tire & 3.50 - 3.70 gear. I'm afraid the glide would be too much of a pig on just the engine.
DONT LOOK @ MY SIG BELOW AS THE WEIGHT REFERENCE WOULDN'T MATCH. I'M LOOKING @ CHANGING EVERYTHING.

That combo is a dog if you put a TIGHT nitrous converter in it(3000rpm) and have 600hp. If you put a 5000 stall in it, it will actually run very well N/A but it will blow through the converter with the addition of nitrous. It still won't 60 as hard as a 350/400 trans but it will also be more driveable on the street at WOT. Final drive ratio is greatly reduced. I think the stat is like 20-30% less torque to the tires with a 1.76 vs. a 2.48 first gear. Don't quote me on that.
My car has a 1.76 PG, 3500lbs, 3.73, 28", 3000 stall now. It goes 11.80's. Same combo and a 5000 stall went 11.20's with 3 additional mph. With a 150 shot however...the 3000 stall goes 10.40's and the 5000 stall went 10.60's. More nitrous obviously would go slower with the big innefficient stall and quicker with the tight stall. 4000rpm would be a better "middle of the road" stall IMHO.
So in the end you really have to choose. Max effort N/A high gear/converter/3 speed OR Radial racing style 2 speed/tight stall/low gear
If you want both worlds...get a 3 speed with 2.10 first gear OR just launch in second and utilize the 1.5 gear...On the street, that may be doable. Endless opinions. Goodluck!

Thanks I know you were trying to help but I really need to hear from those who use this setup now.

What? Again looking for people that have or had the setup and understand what I'm asking. There is a real fine break point with weight and power and a glide for street use and I'm trying to determine where others have found that point is.
