It's been too long for me to comment.

You could pull the head off and all the other extra bit to lighten it. Especially if you're not using it again soon. After you get the head off, Pull the sump off and undo the big ends
crank bolts and pull out the pistons and crank

Or you could spend $80-$150 and get a 1ton block and tackle. And borrow a mate's strong carport/garage roof rafter.

The block and tackle is a good investment if you like to fiddle with old cars. I was going to say "old Datsuns", but I reckon they are more reliable than most cars.
