Haven't read anyone here recommend going over it...nor "I've been doing it for years with no problems"...or..."go for it"...
Unless you have a non computer controlled motor, redline pretty much does not mean a thing in today's motors. The computer shut fuel down if you reach too high of revs, so you can't over rev a motor generally speaking today.
Some like the Dmax I had would only let me get to around 3500 accelerating, but engine braking was 5000 or so.
My idi 7.3, and 6.5td diesel shut off fuel at 3000 and 3500 mechanically.
Not sure one could over rev a motor made in the last 20-25 years, be it has or diesel.
