Subscribing for results. I am building a 441 with ls3 heads, (wegner motorsports ported) Sleeved ls3 block, ls3 intake, and the same cam. A friend of mine just got done with a GTO and 441 ended up making 520, smaller cam, but has stock h-pipe with resonator, thinking that is the problem. Very curious on your results

Well fellas here is what happens when using a Spohn, I contacted them and I told them what happened and I sent the pictures you see below and the you'll see their response. I ordered this d/s through the ws6store and as you can see I ordered the one that applies to me. Spohn's defense is you should of measured and that strapping a car on the dyno causes "stress" well no kidding but more that being on a street? Really? Well then if I have to measure why would they sell their d/s's as stock lengths? And ready to ship? Or th400's or 4L60's or power glides ? If you still have to measure?! I also called PST abd strange this morning and they said they DO NOT make theirs shorter! They both said they make it to exact sizes this Now I'm out a Trans with no days off because of these NATO clowns and All cops have to be on the streets or close by! All I wanted was to have my car ready by memorial day weekend to celebrate it with my family!
What do you guys think?

The output shaft on your transmission broke, it's actually a very common occurence when strapped down to a chassis dyno. A chassis dyno places a lot of stress on the drivetrain.

It had nothing to do with your driveshaft. The driveshaft is exactly as it should be from your pictures. They are supposed to be a bit shorter than the factory driveshaft, you need a little more slip yoke travel for high performance applications. This is how we have built them for 13 years and how any performance driveshaft company builds them. With that said it is always the installer's responsibility when installing any driveshaft on any car to check for proper engagement, etc. before driving the vehicle.
It was just a matter of the stress the chassis dyno put on your transmission, it happens unfortunately.

I use bmr for my suspension parts because of a conversation with a guy from spohn that he come off as being a ***** so I called bmr after that and they got a large order from me that day.... I also have a dennys driveshaft in my car.... Works like a champ

This is what kills me!
It's not the vendors fault but why would Spohn advertise like this?

Just an example

That is bullshit, you cant tell me that launching at the track with a 6k clutch dump is less stress then strapped on the dyno. I have a pst shaft and it has taken many a launch with my 402 on spray and never had an issue.

Their comments are total BS. Although it doesn't get you out of the woods. Everything that is bought has to be checked because you can't count on anyone anymore. Not trying to add insult to injury just stating the facts. Chalk it up to lesson learned cause you won't forget anytime soon. Cut your ties with spohn and go with a PST. Sorry man, it sucks I've been there.
