First off I did search but didn't find the right answer to my question. I am wondering if the Delco EP381 will be sufficient for a Series II 3800 SC running a 3.4 pulley and powerlog manifold as the only performance upgrades? If not are there any other Delco pumps that will work?
Napa - Delphi part DFP FE0102 $129.00 I used this one on my 3.4 setup for a couple years until I switched to E85. This is a stock fuel pump for a 97 bonneville supercharged that fits with minor modifications to the fiero setup.

The Delco EP-381 or other brand equiv. pumps are good to about 300 crank HP on a supercharged engine. With the mods you are talking about running, you should be ok using this pump and it will bolt right in to a 87-88 Fiero tank and sending unit without modification. MAKE SURE you discard the stock Fiero pulsator (plastic and metal piece that connects the factory Fiero fuel pump to the sending unit line) and replace that with the rubber line and clamps supplied with the new fuel pump. If you buy a Delco EP-381 or Delphi FE0114 pump kit, it should come with the in-tank rated rubber hose and clamps you'll need to do this. Get a new inlet filter/sock/strainer for the stock Fiero pump and it will install right onto either of these new pumps.
Rockauto.com and Amazon.com will probably be the cheapest place you'll find either of these pumps at.

I didn't do that part above..... what is that? I'm planning on dropping the tank tomorrow and fixing that, but what is a pulsator?
I just installed a DW 200 fuel pump on a stock (except for 3.4" pulley) on a 3800 SC Series II engine yesterday and it works quite nicely. There is almost zero pump noise and it has a three year no fault warranty. This is not to bad for a $90 pump that is supposed to be able to handle large quantities of alcohol without seal damage.
