Yea totally missed that I said a glide had a 1.48 first gear. My bad I meant 1.80 or 1.76 for those who are extremely specific

[@stevem145]

Stock first gear ratios on a Powerglide transmission 1.82 1.76 the 1.80 that you have is an aftermarket gear set in my opinion you will be very happy with the power glide and possibly a little bit faster mostly happy that isn't broken all the time. I have ran a Powerglide for many years in a 36 plus hundred pound car that 60fts mid 1.3severybody said a Powerglide would not work in and I have never had a complaint.

[@stevenvanheel3932]

V8 glides have a 1.76 and I6 Glides have a 1.82.

Very good video and information. Always thought a power glide, was better for 1/8 mile racing and th400 was better for 1/4 mile. But after this video, I see the power glide is better for higher horsepower engines. While the Th400 extra gear helps out lower horsepower engines.

[@wesdoobner7521]

I've driven a lot of GM cars from the 70's and my favorite transmission is the turbo 350. I would only use the turbo 400 on an extreme build, like a drag car. Even though they might seem similar from the names, they drive totally different, turbo 400's can feel kind of heavy and clunky, 350's are smooth. Also, just for amusement, if you happen to knock your car into reverse while driving down the street, the 400 and 350 react totally differently. The 400 will lock your wheels up and kill the engine immediately, the 350 will kill the engine if you don't give it any gas, but if you give it some gas it will start spinning the wheels in reverse.

[@ryangulley2051]

Actually we had a 400 turbo my friend had in a 72 cutlass 455 engine hit reverse hammering it and we went sideways and the tires were spinning backwards.didnt tear the trans up either

[@riverrat4631]

I have a OBS short, wide regular cab truck. I got it down to 3200lbs. The interior is stripped with one aluminum plate for gauges and two aluminum seats. Truck is back halfed with a 9in ford with ladder bars. Rear adjustable shocks. The roll cage runs from the rear frame over the axle through the cab and runs out to the front frame horns. No inter fenders. The frame has holes drilled for weight. Still running stock front suspension. That’s about to change. I’m installing light weight A-arm and I plan to remove the front and side glass and go with Optic Armor. This should get me close to 3050-3100lbs. Running a big cubic inch SBC with a Built Power Glide. Truck best time is in the 6:50’s in the 1/8th mile. It has a 4:56 gear, so the power glide really helps me get off the line before having to shift and upset the truck. I’m hoping going with lighter front suspension and using Optic Armor I can get in the 6:30’s. That’s pretty good for a full size truck that’s all steel but the hood. I’m a big fan of the Power Glide even for street driving. My truck makes enough power that I don’t need a low first gear to get moving. Plus I have the 4:56 rear gear.. I had several people tell me you can’t run a Power Glide on something over 3000lbs. It’s all about setup and gearing. My truck was setup to race 1/8 mile. I can’t run down the interstate at 80mph for long distances. But at drag and drives I hope to cruise at 55-60mph. I’m excited to try anyway. Great video, sometimes I feel the Power Glides get a bad wrap, but it’s because guys don’t have them setup right. 🇺🇸🦅🏁🛻

[@waynebollentin989]

The lockup powerglide has been around since the late 90s. You didn't see them much after 2004 because they got outlawed in class type racing because people who had them were kicking ass with them. Only place you found them was grudge racing if they were willing to tell you. Once the rule went away they now own just about every record where they're aloud to be used. You can also get them for under 10k as a package. He's right in the fact if you want one of the best out there it's expensive. 15k won't even get it done in many cases. Also the Th400 is popular now with cars making 2500hp+ with the first gear removed. Some keep the 3 gears. Just depends on the tuner. It's not that the 2speed is better it's just easier to get to work. Nice video bro..

[@warmachineracing17]

when running the 1/4 mile in the cow what differences will you see going from the TH400 to the glide? Like does the glide hit your max rpm sooner, because I am thinking you will hit high gear or 1:1 sooner in the glide than in the TH400. Just curious. By the 1/4 mile the TH400 is stretched pretty far in the cow I would imagine so just seeing if the glide is more suited for 1/8 mile passes for you.

[@holtpierce6815]

On power glide can you use Reid case and stock power glide internals. Look for power glide to use in my bracket / super street car. I like the idea of the Reid case for I don't have to use Blankets or external shields. what do you think?

I have an FTI TH400 and matching FTI 3600 stall converter (to keep it somewhat streetable) and love it. Highly, highly recommend FTI! Though with my new combo I’m likely to run into a somewhat similar situation you’re in and may have to switch to a glide. But if I do, I’m putting a gear vendors unit (has been plan for the 400, but haven’t done it yet) behind it and turn that 2 speed into 4speed, sorta;)

Also Powerglide take about half the power to turn compared to a TH400. But I have the TH400 in my 12’ Camaro with a centrifugal supercharger. I do not have as much power off the hit as a proper turbo setup.

[@richardables6561]

I think the new hot setup is the turbo glide. Glides certainly have their place. The downfall of a glide is the same now as it has always been. It might be a lot lighter it also means its a lot weaker. You can make a seriously strong glide but its certainly going to cost. If your willing to sacrifice weight for strength but you still want a better first gear ratio then the 2 speed turbo glide is what the industry has turned to. I think it also depends on where your budget is. If you want something that will work behind a dump truck and is built for pure strength and you dont want to invest 5k in a tranny then a 400 is where its at. The 400 is an excellent option for someone who wants to go racing reliably on a budget. Your going to sacrifice the hp that all that extra rotating mass robs though. If your not so much on a budget and you are shooting for every 100th that you can squeeze out of the car and you dont mind all the additional maintaince then a glide is for you. Knocking out weight is just free horsepower. There is a reason why in stock eliminator and super stock most guys are running glides, 200r4, c4 and 904s with 3 clutch packs in them. Weight=hp. Just my 2 cents though. Nice video thumbs up.

I know most people have their own opinions of how to do it. But how did you do go about burnouts with the th400 at the track? Burnout started in 2nd then shift to 1st once at the line? Or start in first and quick bump to 2nd to finish. then back to 1st at the line?

Good video. I’ve been struggling between what I’m going to run in my 3800lb pickup. Mostly just streeting around and maybe playing a little on the track. Been debating on 6L80 or 4L80. I’m pretty sure at this point the 2.48 first gear on the 4L80 will do me more justice than the 4.05 1st of the 6L. I’m dropping a bone stock Ls3 in the truck just to get a feel for it over the old V6 it had. I think if I kept it stock and just tooled around in it the 6 speed would be the answer, but since I don’t want tons of wheel spin taking off and later want the build/boost the motor I’m thinking 4L. Took my a long time to grasp why a power glide with that tall first gear could be beneficial in any way. But I think I finally get it.

[@gracielittle7702]

Great video.. easy to understand.. but reading the comments I see some confusion over a built PG vs stock PG.. A stock PG is still good for the street in a low HP car say 300-600 hp after all GM put them in 3400 lbs + cars.. after 600hp it's best to put some stronger parts in them up to 1000hp with a blanket or shield of course .. After 1000hp you really need a built PG with a aftermarket case... Low HP cars with a stock PG work better when the car is 3000lbs or less.. Any thing over 3000 lbs street sometimes strip car really needs to be a th350 or th400 to get all that weight moving... After 1000hp it really don't matter.. It will be a built transmission anyways.. 1000hp + cars with a built PG is less weight and gives you more time to settle the car down before you have to shift... Any strip car that's a 1000hp+ a PG is the way to go..
