Well.....I tore some more up today. It seems a stock driveshaft does not like 140+mph @ 6400+rpm. After dinner I will post pics plus a little video as I was taping in the passenger seat as it let go. I am making a few calls tomorrow on a used FLT trans and I need a new (stronger) driveshaft. Also the carbon filter box took some flak hence the mess. Let the fun begin....

Subscribe now, pics coming soon

 

Oh man, subscription in.

 

I wondered why you asked about that old converter I had for sale.

This will be a long thread, people love carnage.

Good luck finding someone that will build a one piece long driveshaft for that.

 

I know It's something in the neighborhood of 64"

 

Subscibing and dreading what is to come...
I'm crossing my fingers that your wrong and it's just the dyno that broke and someone threw a bunch of spare parts under your truck to fool you...

 

these should be some good pictures of how not to test stock parts. lol hope it all comes back together for ya.

 

Hmm......J/K. Video uploading

 

Sorry man. I have tested my new Dynotech aluminum shaft to 7000rpm on the dyno with 2 pulls and performed flawless. I highly recommend. I think mine is 62.5" eye to eye.

 

The bad part is, the driveshaft is the only stock part left on the whole damn driveline.

 

another good reason to upgrade
