It shifts somewhere around 6800-6900ish...

In the dyno graph I mentioned that was in the 360's, we took it to 6800 and it was STILL making power.

Does yours have the 243 or 861 heads? 360 is a great output from a 5.3.

Now, are you spinning that thing up to 6900 on the streets daily? You still running a stock trans? Just curious how detrimental shifting a stock trans between 6500-7000 is.
