Any one who laughs and fist bumps over tearing up parts and making a mess like that is an idiot who I try to avoid. Just sayin'.

Still in gear? Jacks 4000# car up with old jack and crawls under it with no jack stands?

no bueno

That's what I was thinking, you have to be an idiot to crawl under a car on a floor jack without putting a jack stand under the car. shock

I wonder how long that sprag had been hurt, or if he did the damage on the first burnout in 1st gear where it seemed like he pedaled it and also shifted to second.

That's my worst nightmare with a non-LBA valve body. I don't do first gear burnouts but it still worries me.

Can a non-LBA valve body be replaced with an LBA valve body without any other changes, or is it best to pull the trans when you swap them?

I have abused a non LBA manual shift 727 in so many ways it is not even funny. Now that I know better I try to be smarter, by switching to a 904 haha.

laugh2 I know turbo 400's can explode too but you definitely don't see it with the same frequency as 727's. 904's don't do it at all?

904 drums are smaller in diameter so the max speed at the outside of it during an overrun event is slower than the 727 drum is how people on here have described it when this topic comes up.

TH400 can blow themselves apart as well and not even under race conditions. My brother ballooned one real good years ago when it went into passing gear under full throttle. Bellhousing full of cracks and missing pieces and the middle of the case split horizontally upwards towards the trans tunnel so you could see straight thru it to the other side, It happened on a narrow two lane road in the middle of nowhere and some parts of the bellhousing shot out into a field and he never did find all of it.

the first thought i had when seeing that, after backing up, i always drove the car ahead at least 10 feet or so to set the sprague. [over running clutch ?]
i didn't see that on the video when it went boom. did i miss that, or am i just crazy in my thinking ?

This is a prime example of someone who didn't know how to build a 727 correctly to make sure it didn't fail after they worked on it shruggy twocents
Aluminum or steel drums are your friend up

400's like to blow up on the big end... Advantage Chrysler... LOL

As long as you use a OEM drum in a 727, this is the risk you take.

Useless Trashy Garbage with another unique video I won't click on... What's next? "Frame connectors" on a Mopar are bad? Nevermind, he already did that one.

listening to the guy it sounded like he saw he put it into manual low and shifted to second , at least he thought he did that .

I'm still trying to figure out how the trans shifted it self into park after it went boom with the shift linkage ripped off.


running up my post count some more .

Probably dinged the roller clutch on the first burnout. Didn't sound like the RPMs were really up when it broke. She's lucky the stuff didn't get through the floor.

In 2023, this should not happen. It ain't hard to avoid. LBA VB helps and they work well now so why not. Otherwise, a billet drum. Get the OE grenade out of it.

I made a guy pull a 904 and bring it to me once. He had broken a rear, fixed it, and was driving the car around on the street. Everything seemed okay and it was going to the track. I insisted he pull it.

Half of the springs were mashed flat by the rollers when the rear broke. The rollers were loose in the assembly. The other half were still functioning enough to drive the car around. It would not have survived the first hit.

Maybe I'm strange but I don't find these people entertaining nor do I find the destruction of a 727 entertaining.
