Going from 4L80E to Powerglide

Going from 4L80E to Powerglide
I am about ready to pull the trigger on swapping out and selling my 4L80e and swapping in a comparably built powerglide for obvious go fast reasons. I currently have a BMR transmission crossmember and a 1350 steel driveshaft, TCI flexplate and FTI 3800 converter, Lokar dipstick(that I HATE btw), and fan cooled B&M transmission cooler with thermostat control, and a B&M quicksilver rachet shifter.
Now I know about the only things I'll be able to keep is the tranny cooler and the lines to and from it, and maybe the drive shaft although I would like to find a lighter one that is just as strong.
I want the PG for the 1.80 or 1.76 first gear as I'm going to be making some big changes to my car engine wise this winter and I'm looking to shed some weight off this tank. I know I'll need a new much higher stall converter and most likely a higher rear gear from my 3.55's I have now. I was thinking 3.89's maybe 3.73's and a Pro Torque Converter, FTI or UCC 4500-5000stall. What shifter are you PG f-body guys using, and what are you doing for crossmembers and dipsticks? Last thing is the flexplate I'll probably need a new one unless the TCI one will work which I'm unsure and likely aware of it not working with a PG.
Anyone who has made a similar swap from 4l80e, 60e, Th350 or 400 to a PG with a power adder what did you change the stall of your converter to, to account for the steeper first gear, or did you just throw a crap ton more power at it, or a little bit of both? Also what rear gear and tire size were you running before and after? Sorry for all the questions just trying to get all the stuff I need. I wouldn't even think about taking it out without somone wanting to buy it, but a buddy of mines buddy, that I know of has a bottle fed monster of a street/race car and has been wanting a 80e for a while now. It's almost new still with 20-25 passes on it.

I talked to Jon. Deff. interested in the 80e. I can probably get a bunch of power glide stuff too. Maybe we can work something out I know a pretty good trans builder.lol After this race at draggin rights I'll pull my TH400 and stall and sell it.

It'd be nice to able to get someone to just fab the crossmember cheaply instead of buying one or having a shop do it.

I'd figure though if you already had a 400 you have a MVB and you don't have a VSS anymore? So how is your speedo getting it's speed signal now?
Does your 400 have the optional aftermarket 2.10 first gear?
I'm kinda contemplating a 400 with the 2.10 first gear too, but I'd like to just do this once. I've got so many people already asking me what I'd sell them the get up for. Didn't think there'd be this must interest my 80e.

Not stealing the thread or anything, but i have a powerglide i will be selling that came in my car just purchased. It is at Abruzzi racing trans right now getting checked out to see what is inside it. Has aftermarket case and fabbed pan, but not sure of internals yet. Will be letting it go for a real decent price since i already have two! Will post back when i get it back. Chuck

I priced out some glide parts last night we can talk and see which direction you want to go. I assume a aftermarket case and trans brake. I made my cross memeber and tuned out pretty nice. I could make you one. But Bobby could also and he is closer to you. Get my # from jon and give me a call. I won't be able to go this weekend I have a aircraft due out and I'll be working probably all weekend. That and I need some parts for my Nano

Word, thanks for pricing the parts out, yes for sure an aftermarket case like a JW or Ultrabell, dedenbear etc. etc. Yea if Bobby could do it he is a lot closer than you. I think your at least 2 hours away from me, as Jon is 45 minutes and your what at least an hour from his place right? I'll call him today or send him a message on HPJ for your number.

I'm using the stock shifter and console with my PG. All I did was add a block for 1-2 shift positions, relettered the indicator and a 15 minute mod to the cable bracket at the trans. I also added a Dedenbear shift solenoid and MSD window switch inside the console to do the shifting. Everything looks factory and works perfect.
I'm running an ATI 9" @4800 stall and it's a little too loose....

How much was the shift solenoid and window switch?
Is it a power adder application? I know I probably won't be using a 9" converter as those are saved for N/A apps mostly, mine will probably be a 10" unit and I was thinking anywhere between 4200-4800 stall.
I'm still trying to decide what to do about the rear gears as the PG's first and high are the same as 2nd and high in my current tranny. I don't want to offset the the first gear too much though. Current gears are 3.55's.

Here is what I would like to have in my powerglide, not this exact one(wouldn't matter if it was I like it just the same) but I'm guessing this will work well in my application...hopefully knowing the people I do I can get one built comparably or exactly the same with the aftermarket case for the same price.http://www.atiracing.com/products/tr...t-proglide.htm

I am running a VSS on my car, using parts from a 4L80 if I remember right. Its been in the car for about 5 or 6 years now, and I don't remmeber the parts off the top of my head. I might just wait on the PG I have a line on until some other things come together, and run the th400 for now. What had to be done to tap into your ABS sensor?
