Update - last night I borrowed a stand and yoke from OldTee, and an engine hoist from Bill M. Tonight I assembled both before Andrew came over (we had a nice dinner: chicken on the grill, fresh broccoli, rice pilaf, fresh-baked bread (not baked here, though), and Pepperidge Farm cookies), then we put the yoke on the engine:
Raised the engine with the hoist (needed to raise one side a little first using the jack and a 4x6, so it would clear sliding under the hoist). Thanks to TR and OldTee for advice in mounting the yoke, and TR and Bill M for advice hooking up the hoist (I know you'll all find this hard to believe since I'm such a wrench, but I've never done this before). If you're wondering about the wood, it's to keep the chain from pressing too hard on the intake tower - it worked, too.
Following advice from Bill M, we raised the engine pretty high, and lifted the stand to slide it over the yoke, rather than manhandling the engine to get it angled to fit in the stand. Easy Peasy. Other than driving to Darnestown to get the hoist, this was really easy, and could easily be done by one person with limited experience and slightly less limited common sense.
Then Andrew and I took off the exhaust system, except the heat exchangers. Sprayed the nuts/studs liberally with WD-40. Bill M loaned me some special tools, and OldTee is going to come over tomorrow (with Andrew) to try to help get the head exchanges off. Hopefully he'll bring his truck, so we can load the engine onto it using the hoist to take it to Matt De Maria's and get the studs drilled out, just in case. All the nuts came off for the exhaust (most were off last summer) except for 1, which had to be cut off. I'm a little worried about tomorrow...
