should be able to run midgrade. might want to get a tune.. FYI stock tune for B-body LT1s were 87 octane. Then again we have around 10:1 compression, compared to your guys what? 10.3-10.5:1?

The f-body was 10.4 the b-body was 10.0 but with iron heads and everyone knows aluminum allows higher compression.
For a retrofit application you will likely need reprogramming anyway so reprogram it for 87 octane and you will be fine.
If a heavy pig of a b-body is OK lugging the motor with 2.56s(wagons) and iron heads at 10:1 the aluminum head engine in a lighter car would be no problem whatsoever to make run on 87 octane.
If this is a second car you're buying for good gas milage, you're buying the wrong car. You could try lower octane gas but watch for pinging when everything's hot. High octane like it says on the gas door is what you should be using.
