Interesting question was posed to me and I have no good data.
"Didn't all engines have lift (or hoist) hooks?"
I went through Mannel's (see my other posts relating to exhaust manifolds, which is somewhat how I got here) and didn't see any mention of "hoist hooks" until 68. And then with a notation that the factory was supposed to remove them and didn't always do it. Just like tie down hooks.
I did see the video of the engine installation on an early car and the factory just used the exhaust manifolds and grabs them with large J hooks on a hoist. I suppose this changed later due to clearance issues.
Can we (the royal we) construct a list of engines that received, kept or the factory wanted removal of the hooks?
