In stock configuration I wouldn't be surprised if the peak was below 4k. They're pretty mild/low compression engines in stock form.
I wouldn't put the redline anything past 5k for stock, and that may be a little high. Dodge hemi's didn't have harmonic balancers from the factory, so even though they have forged cranks they have a tendency to have issues. You can fit a neutral balance harmonic damper to them, the later LA balancers fit with a stepped key, although then you need to work out the pulley situation. With a balancer out front, a chamfer on the stock oiling holes in the crank and a good balance job the dodge hemi's will spin up as well as any LA smallblock. But stock I would probably do most of my shifting before 4k, and never higher than 5k.
