Titan Engines in Ocala FL remanufactures the 4.0 inline six as a stroker with 4.6-4.7 liters. I have one going into my 2001 Grand Cherokee currently without modifications. They say it will run fine as is and will do better with a variable MAP sensor and 24-lb injectors in place of the stock 19-lb units. Does anyone here have any experience with this engine or its modifications?

If it's not coming with one you will likely need a bored out throttle body to handle the air. You could use a boost-a-pump unit to increase fuel pressure or an adjustable fuel pressure regulator on the rail. Increasing fuel pressure does the same thing as larger injectors, it's your call. I'd probably go with larger injectors and the stock MAP.
Might ask the Yahoo strokers group.
Check the Yahoo Strokers group for some recent feedback on Titan. Also look at Golen as another alternatives. Lower temp thermostat, free flowing exhaust, larger TB, 24 LB injectors, adjustable MAP sensor and an adjustable fuel pressure regulator are all reccommended and probably required to run pump gas without pinging.

Too late. Already got it here. But I will check on the Yahoo group.
The injectors are on their way, I have the parts for the MAP sensor, and a thermostat sounds like an easy swap. But for the cost of the exhaust, TB, and AFPR, I can buy a lot of premium if I have to ...

I dunno about Amazon, but you *can* buy them on ebay ...
