Lifting a Chev
Just in case you are ever in the position to lift a 350 Chev engine with a chain, here's a tip to save you a bit of drama:
Even if there is no lifting point at the front of the engine, be wary of using the natural alternative of looping the chain under the front of the engine. If the chain rests between the harmonic balancer and the sump (a seemingly nice, strong slot for a chain to sit) it will press against the bottom of the timing cover. It turns out this cover is quite thin, and can dent in to rest against the timing chain. Next time the chain operates (when the engine is started), it'll open up a nice little oil leak in the bottom of the cover for you.
Oh, and in case you have to do it, replacing the cover is simply and quite inexpensive. It's the sourcing of parts, obtaining a balancer puller, removing the belts, removing the crank and water pump pulleys, removing the alternator bracket, removing the water pump, pulling the balancer, and replacing all the seals and gaskets that's the trouble.
PS. And removing the sump after discovering the cover doesn't fit properly with the sump in place. And cutting off the old timing tab and trying to come up with a way to fit it in the right place on the new cover, which has a ridge in the way. Grrrrrr.
