Is your 10+ year old cooling system up to the task of cooling a 15% larger engine? What's the condition of your head? You surely wouldn't put a high mileage head on a new short block. I think you get the idea of where I'm going with this.

If you can build a stroker with those parts for around a grand, you my friend are amazing. But back to reality for the rest of us, those parts will be about half the cost of a stroker.

As for the cam selection, the best bet is one made by mopar...either the OEM cam or the mopar performance cams. Crane and Comp Cams have not figured out how to build a reliable cam, and nobody I know of has gotten more than 34k miles before one of their cams has worn out. The Crane 753905 is the most popular 4.0 cam, but it's also the most notorious for premature failure. Do some research, and you'll have second thoughts about Crane.
I didn't know about the crankshaft spacer, I was wondering if you needed anything else to build a stroker. I knew you needed bigger injectors which you can get on ebay for about 150 bucks, but I was just talking about internal wise. 2 bigger fans, and a better water pump should take care of cooling bigger radiator definantly will. You can get rebuild kits without the pistons, for 100 bucks cheaper, and you can get pistons w/ 0-30cc dish for 125 bucks. You can put a stock HO head on a stroker if you want too, but you wouldn't see maximum gains. I don't know how much that spacer is, but if you can do the machine work work and rebuild than you can build a stroker for about a grand.

Alex will you be getting new springs to go with the Mopar cam? I was just looking at the Jeep Connection site and it said they recommend 4529214 springs. They also offer the Mopar cam for 179. I imagine shipping will be more, but you could get the springs from the same place too. Hurry up and do this so I know if its worth buying another cam. Im ordering parts for the stroker.

HD valve springs aren't needed for the Mopar cam. The stock springs are good up to .450" of lift, and I've ran my stroker up to 4800 rpm's without issues. That's with a Crane 753905 cam (.484/.456" lift) and stock springs. That Mopar cam isn't too much more agressive than stock, so it should be fine up the 5200 rpm's.

How many miles are on your engine? Im just asking because of the crane cam failures. I dont think Im going to get a cam for it right away. I know I can get a 4.6 running in the Jeep for several hundred less if I used the stock one. If I want one ill do it right with the all-new valvetrain stuff later on.

A lot of the cam failures have to do with a lack of ZDDP in modern oil or an improper break in method. I don't think Crane's are any more suspetible than other cams, they are just more widely used. Use a good diesel oil and a bottlfe of GM EOS or the like and you will be ok as long as your valve train gemotery is correct (correct preload, correct springs, correct rockers, etc.)

I am also wanting to rebuild my 1996 4.0 that is in my XJ. Its got about 175k miles on it and runs great with the K&N CAI, aftermarket header, and the straight pipe exhaust, but I want to start fresh with it and get it running at maximum capacity and have it forever. I want to put the 91-95 heads instead of the 96 for more power and life, and I also would like to add high performance cams as well. Are there any other parts I can get for my engine rebuild that would maximize flow/power, longer life, and/or gas mileage? If so, where can I find them, or find a deal on them?

On my 87 258, I installed a holley 470 TA 4 barrel, offy intake, rollor rockers, ported head, header, DUI distributer, MSD and the cam I used to tie it all together was comp cams high energy 4X4 cam, part#X4250H. The 258 screams, runs like a small V-8. It makes awesome power in the low to mid range. It's all good, cause the 258 is a low reving engine anyway, it makes peak torque at around 1,800 rpm's, witch is great for off road, it's like a diesel. It's a screamer in the 8th mile. With 4:10 gears it runs out of breath in the quarter, but it rips off the line.
