I'm not the brightest bulb on the tree, but I'm also not the dimmest.
It took me about 10 hours to do it the first time. I could probably do it in 5 this time. Follow the how-to. The book says to take off the exhaust ypipe, which would have made getting at the bolts easier than between the block and the firewall, but my fasteners were rusted to hell. So removal of y-pipe wasn't going to happen. Get at the top bolt from the top of the engine - it's easier, just make sure you have lots of extensions.
The book also recommends removing the drive-axle. I did this and found that I valued the extra space.
Good luck - it's a pain in the arse to remove.
Like EVERYTHING on this engine.
