Supposedly a built 727. Got my doubts!
In this case, apparently, lol!! 4300#(is that with or w/o Her?) tank+512ci+no billet drum=disaster waiting to happen.What's a "built" 727? As in assembled??
Unfortunately, I've known & worked with too many adults that take such childish amusement in these things, it's entertainment to them I guess. Co-worker at dealership I was working at tried picking up a Silverado(fairly long in the tooth), loaded with salt & a spreader w/a full hopper, by the frame in front of the leaves. You guessed it, the frame folded & the rear of the truck turned it into a dump bed. They all stood around laughing like kids at Disneyland, I'm shocked they didn't pose for pictures, moronic. Guy was a hard worker, & decent Dude otherwise, but Ya couldn't see that comin'? Parts guy laughed & commented on it, I just kept workin' and said "that never should've happened". Luckily, the guy worked for the owners, & they eventually replaced the truck with a Dodge. But another tech put the Chebby on the 4-post, then spent a couple hours heating & beating the frame 'till it came back to Earth.Standing around looking at it....will get it fixed real quick.
There ARE things to be learned.............The only people who watch UTG are morons, and slobbering neanderthal types.
I notice UTG still has his legs and possibly his testicles still.I won't fund that idiocy, anybody got cliff notes as to how it went.
Was it being Neutral dropped, burn out or something or just driving.
Or is that **** spread out for visual effect in the picture. There are usually a lot of holes in sheet metal and windows when they let loose.
Best I could tell they were doing a burnout and just jumped on the gas in first and it let go.I won't fund that idiocy, anybody got cliff notes as to how it went.

not a clue, but i seem to remember hearing that when you are building a 727 for a vehicle that does a lot of burnouts (think of warming up the tires for a dragrace) you would want to replace the stock sprag with a bolt in oneI'm a 4 speed guy, is there an instance where the aluminum cases on these are so old that they cant be rebuilt any more? doesn't the sprag "spline in" to the case? I am vaguely familiar with the insides of a TF but it probably has been since the 90s that I've been in one. I may be thinking of the GM Turbo 350 with the center support splining in to the case.
It goes without saying that i think that Chrysler would be badass with a 4 speed even being the heavy car that is is...
They are pressed in on a 727 ... riveted in on a 904 which is why you never see this with a 904.not a clue, but i seem to remember hearing that when you are building a 727 for a vehicle that does a lot of burnouts (think of warming up the tires for a dragrace) you would want to replace the stock sprag with a bolt in one
Yes, & there is a recent thread linking to Cope's vid & explanation of this. Even if You have band apply in manual low, if You shift into 2nd w/o a manual VB & roll-out & the tires bite, the trans shocks the sprag when it kicks back to 1st. So, full manual or stay in 1st, AND this combo if any ever did screams billet drum. It was supposedly "just built" for this car, there's the real muck-up....The sprag is not the real issue. It's the drum. The sprag failing creates the issue where the drum fails. If the drum was built better, the sprag failure would be moot. 904's don't have this issue. There have been explosions of billet druims in 727's, they are rare though.
Generally the sprag ring doesn't spin, the rollers and springs get shocked/smashed up and all detent is lost to hold the rear drum. Then the front drum can go on it's merry way above about 12K rpm, reach critical mass and boom.
Poor burnout technique, letting the tires bite while still in the throttle in first gear out of a burnout, breaking an axle/driveshaft, rear gear can roll the sprag making the "safety"/design feature of the sprag disappear. A low band apply valve body can help, not a guarantee to save a sprag.
