Was looking for factual and solid info. on weather the 6r80's 5th gear can handle a few seconds here and there running in 5th at wot @ just under 800rwhp and with stock converter.
I currently run 3.55's and I am limited to about 155-156mph in 4th and am looking to do a couple half mile races this summer and was wandering if the trans will take a few passes going into 5th and running in 5th to about the 170 mark +/-. Any real world info would be greatly appreciated- I don't want to switch rear gears unless I really have to- I understand when things are modified there is no cut and dry 100% answer was just wandering if any one has any real experience with this.

In general WOT in OD gears is bad news, and I'd say if you don't cook up the smaller set of clutches, you may put your motor at risk. I'd consider taller rear tires as a stop gap here if you don't want to go down in rear gear ratio.
