^^Should make for a real good race. My money is on Z unless AC can really launch and row through them gears, gonna need some vids!!
Unsure on the HP limits but rpm wise the general consensus from reputable people seems to be 6400/6500rpm or so. I revved mine out to 6900/7000 b/c messed up shiftpoints once but I wouldn't imagine that to hold together for long. I personally do not care for spinning past 6400 on a stock block.

It probably won't spin a bearing the first time you hit 6501, but it will eventually.
Figure out how much risk you want to take and go for it.
Just understand the cost of rebuilding a bottom end when you break it.
If you can't afford it, stay under 6000
(and yes, you will hear 100 stories from people who "run 6500 every day and never have a problem")
RWHP ... in the 500-550 range is doable.
Again, the more you push it, the sooner it's gonna shell.
Typically, a 400rwhp H/C motor with a 125shot is considered "safe"
Push it as far as you want to, just understand the implications.

I hear ya James. I recently had Ion lower the shift points down to 6200, from the 6400 it had for the NA runs. Kinda running out of rpm on the big end though. It's not real bad, and I've heard it's better to run out of rpms a "little" early then the other way around.
