How old is too old to work on Model A's???

[Marshall V. Daut]

I normally start with a bare block with adapter attached, which I can still lift by myself and slide into the engine stand's receptable. Then I build up the engine from there. But this time it's a 160 pound short block. A bit heavy for me. So, I like your idea. I can't see what the chains are attached to in the small avatar photo: manifold studs through the chain links secured by nuts? Or grade 8 7/16" hex head bolts through the links? Either should do the job.
