Hey guys, Just wondering what the fastest speed any of you have traveled in your trucks. I was on a straight road with my diablo yesterday and I got my sierra up to 136 mph. I looked like it could have done more but a car was up ahead so I slowed down.

127 is my top, but that was on a dyno, and in 3rd hear.......

So I imagine somewhere around your speed, on a LONG STRAIGHT road!!

Little over 120 before the cam and without nitrous.
But with the 408 if I can control it probably a little over 140.

Just looked at the video I posted the other day and at 120mph I was about 4900rpm.
That means I've got about 800 more rpm to pull. I wonder what I could hit??
