HAHA you need to do some research!!! As Chris and Diata have said there is alot more that goes into a swap than just putting the motor in and driving away! To do an LS swap you need alot. First off unless you are really good at reading wiring schematics and then understanding enough to rewire and repin connectors which most people can't to this magnitude including myself you are going to need to buy a complete harness from Current Performance wiring or others which start around $750. Then you need to figure out motor mounts. Either you can make them yourself or buy some with either option comes the chance you may have to move the motor forward or back a bit. Once you have that figured out you have to modify a oil pan to work for the 4x4 chassis. I belive you will also have to swap out the flexplate to match up the trans. Once the motor is situated you may have to modify the trans cross member to fit properly. Once you have that accomplished you have to figure out things like the ac and other motor accesories like Chris said unless you run without it. Your options are to notch the frame or use alternate brackets to top mount it(no I'm not telling you what will work for this cause it can be found online). Once you have that figured out theres still the issue of how you are going to cool the motor. Most people modify the core support to move the rad forward and run electric fans but there are other alternatives out there that can also be found with a bit of searching. Oh and then you have to run headers and custom exhaust. You will need a tune to run the motor. Then there are always a million different things that pop up on every build I have ever read to deal with! If you have made it his far then hopefully you should be about to drive it out of the garage and be on your way. Just because the motor is cheap doesnt mean the swap is cheap!! You are honestly looking at another $2k conservativley on top of the motor cost to do an LS swap unless you are really crafty and patient enough to spend the next year gathering parts as you find them super cheap. I love watching these swap threads but I just wish you would spend more time researching and finding out what you are getting into rather than taking the lazy route and wanting everyone to tell you how to do it. Keep us updated if you end up doing it please

ok.... i must say that i have spent hours trying to sift thru all the "search for it" replies and rex has the best answer i'v found in a long time. it would be so so nice if people would answer questions in stead of spewing crap out there mouth. i'm just tired of searching and getting no results. and i have never posted a question cuz i know someone will just be like "search for it" wtf why do you think i'm asking cuz i have searched and have "NOT" found the answer.
