That's provided that the limited/base models use the same hardware as the SRT. Based on experience I tend to believe the AMG built engine would use better grade hardware such as ARP for example.

Since his question was max horsepower for a normally aspirated engine the crank should be fine. If you started spraying or boosting then the crank becomes a liability.

LA sleeve carries a full sleeve kit for LS1's for only $750, not bad price for speed parts, granted you do have to hone them to fit your piston.
That would be awesome if there was a reasonably priced stroker kit for us.
