The case spun between his legs and luckily one of the tranny lugs bent the chrome moly cage but stopped it from spinning. A piece of the case hit a guy in the stands in the head. another guy passed out when he saw the blood and fell in the stands. When the trannt blew it ripped 3 morse cables going to the engine like they were toilet paper. The tranny blanket looked like ground up fiberglass. Very scary day. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

Out of curiosity do you back up after your burn out.. you need 4 or 5 feet to set the sprag minimum(going forward)... to be honest I'm not sure if you have to do the same thing after being in neutral but I always give it 5' or more

Just redid a 904 for a friend that had this exact same thing happen, rolled the sprag,broke the case and cleaned the splines out of the planitary,,but did not explode the drum. so yes check the rear end. Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

He did not have the shield on the trans and when it went the ambulance took her away. I had to replace the trans tunnel and a portion of the drivers floor. Very scary business to say the least. The moral is don't race without the correct safety equipment in place. 1957 Power wagon wm300 original 10.000 mile truck, 1964 dodge Polara Convertible numbers matching

The difference Chevy people listen to each other and will not dare run with without the safety provisions on their 400's. Not really. TH400's came with two different sprags. The HD one is twice as strong as the other but if either one fails the trans loses 2nd gear. The direct drum does explode in TH400's but that's from either shifting into neutral at the finish or shifting into 2nd with a manual valve body. If you leave it in third and coast/brake down it's fine. I ran mid 10's for a year with a TH400 out of a junkyard with nothing but a new filter. They are tough trans. When left fully automatic they are very easy to tweak the shift points with wights and springs behind an access plate. They are heavy, soak up HP but they are tough. I bought an adapter bellhousing to start running them over 727's. Cheap cores, cheap parts. 1967 Coronet, 1989 Daytona tube chassis.

I have a stock drum in my car and always worry about it but havent had any issues in the last 4 years. I also worry about the 8 3/4 but now that I have around 100 passes on it and it still looks like new I am starting to think its good to go. My car only weighs 3800 lbs and only 60' in the high 1.4's. I am very carefull to do 2nd gear burnouts only and it never spins and if it does I will be shifting not pedalling it. Last edited by dragram440; 07/12/13 01:06 PM. 67' charger 499 RB 10.57 at 127

Was there any indication or something seeming not right just before the boom? With high-stall converters the brief flareup in rpm often isn't noticed by the driver. I've known some veteran drivers who, even when they sensed the flareup, couldn't get out of the throttle quick enough to save the trans. The INTERNET, the MISinformation superhighway
