Fire up prechecks

[Teeej]

The 4.0 in my TJ broke a piston skirt, ended up doing the math and decided that money is time, and as much as I would like to build a stroker from the ground up, it was more economical to swap in a new ATK 4.7 with stock heads and cam. It's my daily driver so buying a different mode of transportation was inevitably in the equation if I built her from scratch, as I've built motorcycle and small engines, but never taken on a full sized engine build, so I figured the ATK would be a good start as I can add a cam and head later when I'm less strapped for cash and time.

What I'm wondering is...

Fuel:
Will stock injectors work on the mild stroker? What about Neon injectors? I did some searching but just find specs and charts that don't really make full sense to me. I'm not starved for power, just want the engine to run well and be reliable, not fuel starved, or running lean. Should I buy an adjustable fuel rail? I'm still trying to keep this build budget friendly, but with Jeeps, that never seems to work out haha.

Computer:
I read somewhere I can't presently remember that when messing around with the engine parameters, there is some way to reset the PCM and put it back in learning mode so that it adjusts to the new stroke and injectors. Anyone know it offhand for a stockish 2000 TJ?

Cooling:
I have a stock plastic and aluminum radiator that worked like a dream in the stock 4.0. Never overheated except once when the water pump was finally unable to circulate coolant due to the fins all falling off from degradation. Will this radiator be able to handle a 4.7, or should I spring for an all aluminium?(single row/2 row?) Should I mess with a different Thermostat temp? I was hoping to build the rest of the engine accessories around the engine over time, but I don't want to risk a new block if a stocker is inadequate. That said, I'd be happy to keep the stocker until she starts leaking if it doesn't pose a real threat.

Clutch:
I wanted to throw a new clutch on her when I button her up, but I'm worried with the engine break in period, the brisk sprints to 60mph off the bat in order to set the rings will wreck havoc on a brand new clutch that isn't worn into the flywheel(or pressure plate for that matter). I have a centerforce with probably 85,000 miles on it. It looks like it has some life left on it, but if I can replace it now, it'd save me from having to pull the tranny off the engine one more time. If I go with a new clutch, should I go for a stage 1 or heavyduty clutch kit? I've been looking at ebay specials, and haven't heard bad things about any of them, but I'm disappointed with the way the Centerforce stage 1 performed in traffic, although that's my fault for failing to replace the flywheel(gimme a break, I was young and inexperienced), but I forked out more than $300 for just the clutch, when Ebay sells clutch kit + Flywheel for 200.

Sorry for the inexperience, this is a big project for me, and I'm pretty clueless at the moment. I'm pretty broke, as any Jeep owner is when their Jeep evolves, so I'd like to keep the additional cost down as much as possible, without cutting any corners. I haven't had the time to really do enough homework, as my original engine self destructed rather suddenly(luckily around tax return season) and I pulled her apart and out mostly by myself. Any feedback is appreciated, as I haven't been able to find much info on a stockish stroker, mostly builds that resemble my wildest dreams. Even links to similar threads will be appreciated.
Thanks in advance!

1. The stock injectors might just work on a very mild 4.7 stroker making up to 230hp so they're worth a try.
2. The stock computer should be able to adjust to a 4.7 stroker with the stock cam & head.
3. The stock cooling system works fine on a mild stroker.
4. The stock clutch & flywheel are also fine.
