I didn't have to unhook my starter cables.I just took out the battery and the cables were long enough to let me lay it in the pocket where the battery goes.
This is a vid I made that shows a bit of it.Keep in mind there are three bolts that hold the engine to the cradle that appear to go into the head.Those were missing from mine when I got it so I didn't mention them in the vid.They're right across from the bolts at the base of the block though.If you look carefully you can see where they go in the video.I'll even put an annotation on there just for you.
So Brew, 20 minutes eh?Maybe we all ought to get together and have an engine swap challenge.
