I just got the car and its low on gas but Im not sure what to put in it. Ive heard they dont run well on 87.

Should run on 87 fine, their meant to from the factory, as long as it doesnt have heads or something that changed the compression.

Ok, great.
The motor is internally stock with just external bolt ons.

The cheapest 87 here is $2.899.

Is the timing advanced?

Not that I know of.
I filled up with 87 this morning and its running fine. Its a bit of a pig on gas but I expected that.
