It isn't so much the stroker itself as finding valvetrain parts of the same quality installed originally. Add the larger cams everyone runs in a stroker,plus the lack of zinc in engine oil and they have more issues than an original 4.0l.
I also only run #24lb injectors.but haven't taken it through extreme elevation changes. Some day I'd like to get it tuned by flyin ryan.
I would probably just run the stock cam myself, and something like VR-1 10w30.
