RPM Redline

Does anyone know the RPM redline on a 2017 Ford E450 6.8 liter engine? This is the first tach I've seen that has no mark, line, nothing that indicates the redline. I purposely would not run it in the redline, but I would like to know what it is.

Don't worry about it: the computers will NOT let you over-rev it.
You could Google around a bit, and find it...

Don't worry about a redline unless you have a manual transmission. But I don't think they make any MHs with those.

But I am guessing, somewhere about 5,000 RPM.

The redline for all models of the Triton V-10 is 5,200 rpm. This is based not on the engine per-say, but the speed of the counterbalance shaft located under the valley cover. Many complain of the split pin crank design, but it has proven reliable of it 200,000 mile design life. With max power of 320 @ 3,900 rpm, you will never see the engine approach this rpm when acceleration. If you approach this rpm limit in a low gear of the transmission when descending a steep grade, the transmission will up-shift, regardless of the position of the shift lever.

I know what the red-line in our V-10 is going up a steep grade... it's WAAAAAAAAAAA!! until it finally gets up enough speed to upshift!!
