Stroker?

Well after searching into a V8 swap for a YJ and realizing how much of a pain it would of been to do the conversion I've decided I'll go with A STROKER. I dont plan on anything crazy probably just a poor mans stroker. I need some help putting together the parts I will need. I plan on finding a 4X4 cherokee with a blown 242 and rebuilding it so my jeep won't be down as it is my daily driver. I've done a few nights of drooling and research and have decided this is the best route for me. If one of you jeep gurus would let me know what parts I need I would apreciate it. Shooting for around 230-250 hrspw.

For the price of a long block I dont think so lol. From whatI've gathered its far cheaper to build your own kit.

I think I'll follow this thread. I have a 4.3 for a swap, but I'm still open to options. Good luck.

It may be a slow thread as I'll only be able to work on the motor when I'm off.

I know a bit on this because I was planning to build a stroker myself before i picked up a 350 and 700r4 for dirt cheap running great with 80,000 miles on it. (Being nice to neighbors pays off ) So A 4.0 is basically the same block as the 4.2 but heres the difference. The crankshaft, rods and bore of the pistons. The 4.0 has a smaller stroke then the 4.2 but a bigger bore. So to get to the 4.6 or 4.7 get yourself a 4.2 crankshaft and rods. It should go into the 4.0 with little to no machining. Next it probably would be a good idea to put in some new pistons since you have it apart (this includes rings) So why not bore it out a bit more for more power and more displacment. You can safely bore it over 0.03 but id go with 0.02 to be safe. And you can also play with the compression ratio if your up to it to try to squeeze out more power.
