Magnum 360 rebuild, need advice

I am in the process of rebuilding my magnum 360. I have a goal horsepower of 350-400. It is in a 1998 Jeep Grand Cherokee 5.9 with a 46re transmission and 44a rear end. All wheel drive with dana 30 front. Was thinking about a stroker kit, but the only one I can find is a 408 stroker and I think that may be a little much for stock drivetrain to handle. Is there a smaller stroker kit that will get me to my target hp? for the 408, does the block need to be notched? Any advice or guidance how to get where I want is greatly appreciated!
