How modified is this truck? If it's got a stock valve train or stock springs, it could be valve float...

No, it's aftermarket valve train; ie. valve springs, and pushrods. I know it isn't valve float, because every other Hemi uses the same springs and some with larger cams and they have no problem. Plus, I can run a gear out and it bounces off the rev limiter (Fast and the Furious style, lol) when I hit 6200. Thanks for the advice though.

Maybe once Johan gets finished with the Trinity he can figure something out.

Why are you wanted to shift above 6200rpms? Do you realize the Hemi doesn't make any more HP after 5400rpms! As a matter of fact, the HP level drop like a rock after 5400rpms. So at the 6200+rpms you want to race that good ole pushrod motor to, you'll be squeezing for maybe 80hp.
Sure it may hit harder and feel like a strong machine, but your gonna burn up your tranny and motor running it to 7k that's for sure. i can see maybe 6k, but certainly not any higher.

Do you realize that my motor has a much bigger cam and upgraded valvetrain and many other mods that supports it running past 5400 rpm? I am not wanting to run to 7K, that is just what Johan set my rev limiter and shift points to to see if what he was changing actually worked. I'm not going to burn up my tranny running past 6200 rpm, or my motor. There are plenty of people with bigger cams than me that rev much higher than I plan on revving to.

At the track last week, my buddy was manually shifting it at 6500 lol

Hey Johan, since the Trinity is done can you look into the rev limiter issue? So far every 07-08 guy I've talked with has the same problem as I do. I'm trying to get some of them to post in here as well and see if you can come up with a fix.
