Its an archaic engine design that doesnt do much for maximizing power. Pushrod engine, etc. blah blah. Basically, the engine in my 2002 maxima makes 15 more FT lbs and 63 more HP at the wheels than my jeep makes at the crank. And before you ask, yes it does make more tq than my jeep at 2k RPM...at the wheels
I love my jeep, but efficiency of this engine is lacking. It lasts a long time though! Though not as long as most import engines of its time do

PS, if it made any sense I would swap that engine into the jeep in a heartbeat. It's been great to me no matter what I did to it. Including make over 200 wheel tq at 2000 rpm and still make good power and tq at 7k. I'm not ripping on the 4.0, just saying it's not a real great design, just the same ole same ole that Chrysler was putting out since the 60s basically (they added electronic ignition and fuel injection, besides that it's the same tech that my 69 chevelle engine had). My maxima would definitely cry if I took it through mud and rocks and water, its a street car. Engine would be just fine though.
Cliff notes? It's a good engine, but with a little tech it could be a lot more

I think everyone got off topic with this one. The OP was just asking for pros/cons of a stroker 4.0 and wanted to stay away from an engine swap. But I do think a good 4.6 striker with a mild cam and some head work would make a great DD and not cause any computer issues. Maybe just swap in some 704/784 injectors at the same time and enjoy your new found power.
