First thing I would do is tear the engine down and get into a shop. Make sure the block is good and also verify that the cylinder bores do/can agree with the pistons you want so you know exactly what to get. Then get the stroker kit, have a machine shop install new cam bearings, and install/balance (some offer balancing the components before shipping) the bottom end.
Just be sure to work closely with the shop that's doing the work, everything down to the material that the pistons are made of is going to contribute to how they need to do their thing. Reason I suggest a shop is if the crank needs turned or any other maintenance, they will get the right bearings. Save a lot of hassle on your end, a small mistake can turn into an epic failure.
Either a 5.0L or stroker 4.0L are going to be expensive. No way to narrow down a good estimate on what it would take for either, all depends on who you know...
