You could sell it and build what you want or trade plus$$$$'s to someone that wants more. If you're like me you like performance but don't need maximum horsepower. "Too much" is fun to drive but not a enjoyable cruise.
If only Tim was closer, I'd trade him the 408 in my power wagon, it's a low compression stroker, roughly 8.5:1 but makes 437 ft lbs and right at 400 horse flywheel, with a mild cam. Only 1300 miles
