if your gonna do it yourself, take the trans and transfer case off, you can prolly leave them to together or spit them if you want its your choice, but make sure you dont leave the trans on it will b a lot lot easier. also, if you can get the oil pan off before the engine is out by just lifting it off the mounts and seeing if you can clear the pickup tube, if will be a lot easier to clear the firewall overhang. if you get the trans and pan and oil pickup off the engine will come out smooth as butter without having to perswade it in any crazy ways. i made the mistake of leaving it all on and i will tell you that that overhang will get bent and it wont be fun. i wound up having to use a 2x4 to pry the engine out. and just take off the hood, its 4 bolts and takes about 5 minutes and then its out of your way. but if you already have the head off you might not have as many clearence issues with the crossmember
