Here is info on firing orders.
In 1985 the order was changed on the 302 (5L) to that of the 351.
So the 87 will be as follows 1-3-7-2-6-5-4-8 with number one still being the first cylinder on the left when you are looking at the front of the engine.
For reference the 302, 84 back is as follows 1-5-4-2-6-3-7-8
The camshaft lobe sequence is what controls the firing order in these engines as the 351 cams can be used in the 302 by just changing the plug wire sequence to match the cam.
