I believe many stock engines in the 1960s saw 10:1 and even 12:1 compression. I believe some modified engines in the 1960s even saw 14:1. You were able to be 104 octane at normal gas stations.
In the 1970s this dropped like a rock due to emissions laws, unleaded gas and fuel shortages.

Our 1931 model A is 4:1.
That's partially due to the quality of fuel they had back then but it's also partially due to the engine's design. They make a "high compression" head for the model A that is a whole 6:1 and many guys end up with knocking.
Point being, there is a good chance your 307 will knock on 87 octane if you use even a little boost regardless of how low it's compression is. Engine's of that type typically ran 9.5:1 and specified premium fuel and that's without boost.. You might get away with a little boost running 93 but I wouldn't expect anything huge without major mods.
I know you're not actually considering doing anything, but since it was out there I figured I'd respond to it.

It's been 30 years since I first saw this movie and I think it's held up pretty good.
I need to get a copy on bluray.
