I appreciate the confirmation for the stories I've told others for awhile now, about their trans choices! Funny how years later... guys you told when they asked for advice, about going BACK TO A 400... fianally tell you that they should have switched back then! Solid info young man... Thanks again. Seth
I don't have any transmission videos out for my builds but for over 20 years of building gm racing transmissions in the Cleveland area, I have never been able to help anyone understand all of your points since most guys already have their minds made up. Getting to work with Rossler, Abruzzi, and perfect converter along with picking local drag racing legend Al Goshling's brain has taught me all the tricks. 2nd gear start 400s have been around a long while but again most guys have always underestimated the th400 that even with simple upgrades like using an Ultra bell with 4L80e direct drum and wider bands with full manual valvebody can turn a basic 400 into well over 800hp range with a long lifespan for a street/stip vehicle. When you started with the first answer about difference between them is the overall COST! I had a good laugh since that is the same thing I always say when I get asked. GM engineers made the th400 into a true tank able to drive under land yachts and 1 ton trucks with bbc power in which a factory powerglide case would simply crack the case under such heavy loads. Will sub to channel for more good info. 👍
$7k-$8K for a built powerglide... When I swapped out the powerglide in my '68 camaro for a Muncie 4-speed in the early 90s, I couldn't give my powerglide away. Where was the internet when I needed it? ;)
If going with the 1.58 low gear in the 2 speed 400, would that make it feasible to use on a 500hp/700tq big block car @ 3200 lbs, on the street? If not, what low gear for it could I use? If the 400 isn't advisable, what a powerglide low gear would you recommend for this application? Oh, and what is the power consumption for each of these?
If budget is no concern and you have the rear axle ratio capability to run out the back with no over drive, it’s hard to argue against a max build 400. The 400 has any aftermarket part you could image and are proven to hold up to 5000hp pro mods. Just be ready to get deep in your pocket if you want one for a 2000+hp 4x4 diesel for the swap is going to cost you between $30-35k

Keep that content coming! We appreciate it!
Great video! You confirmed my choice in running a TH400 for my build. Great Content, keep the videos coming! Earned my sub.
Good video..
1500hp blown alcohol 14klb monster truck here. I wouldn't ever run a powerglide. People running them are swapping them out each show just about.
Can you make a video showing how the 2 speed 400 works? What parts are used to make a 2 speed and what parts are left out.
If going with the 1.58 low gear in the 2 speed 400, would that make it feasible to use on a 500hp/700tq big block car @ 3200 lbs, on the street? If not, what low gear for it could I use?

Great video.
Thanks JP
What parts are you using to make a 2 speed th400 ?
Could you use a 1 speed power glide instead for lower hp applications?
Is a turbo 400 stronger than a max built 48re?😊
