Hey Tod, the best way i think is to do a search on here and type in 6cyl or i-6 or whatever and just read through the post. Im doing the same thing with mine, actually putting in a 6 and getting all the mods done. Im getting it done up in Reno saving me about 6000$ on all the stuff im doing. But to answer your question try searching here, lots of URL for articles in peoples post.
Dont go to Western Auto and w4d in Reno NV, they stole 11,000$ and 7 months of my time to get my jeep back with junkyard parts... and i cant even sue them... live and learn
