Always a difficult decision.
Here is what I can come up with (and I know there are pros/cons that will point to the 400 over the Glide):
1. Simplicity. There isn't anything much more simple that a Glide. However, I did not cut corners with the one I am going to use. It's built for plenty and hoping I don't run into much for rebuilding/refreshing (year right, I know better).
2. Weight. Need to cut weight any way I can with the Trans Am being so heavy. I know I would lose a little going to the 400, but even more going to the Glide.
3. 1st Gear. Going to a Glide should give two advantages with a 1.80 1st gear. The first, it should really tame down the launches (wheelstands). I feel I had a little better control on that now, but this change should simplify (more forgiving) than the 2.10/2.48 options. It should also simplify traction on both the track and the street (doubtful).
4. Simplicity. Yet again. Just a single gear shift. I love the computer controlled shifting of the 4L80. I figure a 2 speed with a single shift shouldn't be too bad. And with a 1.80, it will be a little while after the car has launched. No need to have more going on than needed.
I know you could argue the other way on each and every one of these, but I think it will work the way I am hoping. I know it will be a huge change especially from the street driving aspect.
And I understand that the 400 would probably have been cheaper. However, by the time you get an SFI case (or applicable shields), and a 2.10 1st gear, the cost significantly increases anyhow. Either way, I think there will be an advantage with a transmission change.

Received my rear window molding late last week. Was able to get the glass guy over here to replace the rear window.
Before:
Going to miss this guy:
After:
Yes, there are lots of fingerprints on the window and also the car is filthy. Wanted to grab a couple of photos tonight but didn't want to clean it due to the glue drying.
It is the light tint on the rear window.

I don't. Nothing special when washing. I have typically used a Meguire's Car Wash for washing the car. Every once in a while I talk my buddy slow94formula into buffing the car (probably due for that!). I will only be using a glass cleaner as recommended on the Optic Armor.

My 9.06 pass, it made 7lbs in 3.1 seconds. 11.90% slip in 3rd at 160mph.
On a 9.24 pass, it made 8.2lbs in 2.8 seconds. 10.47% slip in 3rd at 153mph (last years combo with less power).

Will be making a few changes to the car over the next couple of weeks. I am hoping to be able to sneak in a couple more outings this fall before snow. I have a minor surgery coming up and that might delay a few things.
I received my rear molding so I will be changing over to the Optic Armor rear window.
I will also be converting over to a Powerglide with a PTC Converter. I am planning to pull the 4L80 and have it freshened and then will put it up for sale. Will be selling all components to change over:
Jake's Stage 5 4L80 with D3 Brake, Auto Shift
Rossler Moroso Aluminum Deep Pan and Filter extension
Madman 4th Gen 4L80 Dipstick
Midwest Chassis Lightweight Tubular Crossmember, 98-02, 4L80
Circle D 258mm Triple Disk 1B Converter
And PST 3" Chromoly Driveshaft
Holley 4L80 Transmission Harness
Hopefully can sell the components as a package, but will consider individual sale when I get everything pulled. Will get the transmission freshened before putting up for sale.
Looking forward to see what I can run with the Glide. Hopefully will get 2-3 track outings before the end of year.

Some weights of components I measured tonight:

Circle D 258mm Triple Disk Converter: 42.4lbs
PST Chromoly Driveshaft: 20.4lbs

The new Transmission showed up on Thursday from Rossler. I was extremely happy with the service Carl and his team have provided. They were very easy to work with over the phone to specify exactly for my application and discuss other options. I also had the transmission in under 2 weeks from order time to my driveway. I couldn't believe it!!
It is a Rossler Terminator 6, with a Reid 2 piece case, 1.80 low gear, and blow off valve plumbed to the case.

I haven't received the converter yet, but wanted to set the transmission in the car to measure driveshaft length.
It is amazing how much more space there is from the mammoth 4L80. The bolt holes are actually visible from behind.
Going to try to get everything wrapped up over the next two weeks and hopefully back to the track.

It is getting a little closer. I had a few more goodies show up.
The new converter spec'd by Dusty Brandford came in late last week. It is a 9.5" from PTC with a 15x45 stator.
I also got a 3.75" Carbon Fiber driveshaft from PST. I have a Strange Chromoly Yoke on it. Driveshaft was 45-3/8", center to center.
I have an aluminum flexplate ordered from Circle D. That is scheduled to arrive later this week. Will throw everything in the car and hopefully make it to the track on Saturday. Can't wait to test this new combo out.
Old Combo:
4L80 with no fluid: 180lbs
Circle D 258mm Triple Disk Converter: 42.4lbs
PST Chromoly Driveshaft: 20.4lbs
New Combo:
Powerglide with no fluid: 105lbs
PTC 9.5" Converter: 31.2lbs
PST 3.75" Carbon Driveshaft: 12lbs

I received my new Circle D aluminum flexplate on Thursday. Got the flexplate, converter, transmission and driveshaft installed. Also revised the wiring needed to transition from the 4L80 to the Powerglide. I took the car out for a little bit of street time on Friday night and to get ready for a Test and Tune date at Cedar Falls Motorsports Park on Satuday.
The weather didn't look promising as it had scattered misting and rain at Cedar but pulled the car down anyhow. There was a fairly good wind as well as light misting. The track took some extra time spraying and dragging the track.
My buddy asked what my plan was for the first run due to the track conditions. I said we will have to see but probably a half track hit. I was the first set of cars down the track.
I launched the car, hooked, and it felt great. By the 1/8th, it still felt great, and I decided to run it out the back. I had seen the high MPH on the speedo so I figured it was a pretty solid pass. I pulled around to the ticket booth, took a peek and saw 8.62@160. I was pretty thrilled and a significant improvement.
Only got a video of the launch as he didn't expect me to run it out:
From there we adjusted the two step, boost, and minor suspension tweaks. We out for the 2nd pass. Basically it was about the same. But an even better reaction when I saw the slip.
I basically was thinking: damn, finally this thing is doing some work.
Made another minor adjustment to the two step, boost, and suspension and went out for the 3rd pass. I launched the car, hooked, and then started into a power wheelie. My first thought was, here we go again. I stayed in it and it just rode out really nice. It was awesome. The next thing that came to my mind was, oh crap, I have to shift this thing. Just touched the limited but grabbed 2nd, and went through the traps. Grabbed the slip and thought, hot damn!
Needless to say, they closed the track for the day due to safety concerns. The mist on the track was having some cars slide around. I was pretty ecstatic for the first outing with the new transmission. What a great outing:
Looking forward to sneaking down there again once or twice this month yet.
So far I am LOVING the Powerglide on both the street and track. It is amazing.

I bought the Garrett core from Boost Resource. I bought the billet ends from Treadstone. Nate (LS1Nova) with One Guy's Garage build the end tanks and welded the rest of it. I know he has sold at least one and maybe a couple after others have seen mine. He will know exactly what you are talking about if you contact him. Just throw me out there as a reference.
Some data from my 8.30 pass:
Intake IAT when I got on the transbrake: 87 degrees
Intake IAT at 165mph: 130 degrees. 43 degree rise.
Was seeing about 2-4psi pressure drop across the intercooler.

I was reading on yellowbullet so I was curious. My junk intercooler on 15 psi rises 80 degrees in a 1/4 mile pass ending at 180 degrees. This was when my turbo pulled hot under hood air, I have yet to test it now that I built a cold air setup. I already have overheating issues on hot days so a garrett core kinda concerns me.
