in the process of building this thing and am trying to stay ahead of the build. i need to find the most economical fuel tank and pump setup with new lines that i could find. i was reading that the stock tanks are baffled and good. i am doing a frame off so would like to have it all new under there since stock tank is corroded. i will be N/A for a while til i can build the system. this is going on a stroked 6.0 ls.

Easiest, cheapest route would be stock tank, sumped by you. You'll need at least 1/2" lines, probably 5/8". Go with a high quality pump, mounted AND wired CORRECTLY.

Was reading up about a stock tank that has an internal sump (efi) but not sure the model #. Do you know if 1/2 is an8? Maybe 5/8 is an10?

You would be looking for a monte carlo with the 4.3l FI motor. They had the larger baffles from the factory and would be a correct filler neck.
A 3.8l regal turbo tank, 84-87, would also have the larger baffles, but, you would need your filler neck.

Easiest IMO would be a 20 gallon aluminum fuel cell in the trunk.
20 GALLON/78 LITER POLISHED ALUMINUM RACING DRIFT FUEL CELL TANK+LEVEL SENDER | eBay
However, for racing purposes, it is overly large and heavy. Black Tank / Aluminum Cap. Blue Tank / Aluminum Cap. Red Tank / Aluminum Cap. 0-90 Ohm Fuel Sender. Polished Aluminum / Black Cap. 1 x Aluminum Fuel Tank.

Yes, 1/2" is -8 and 5/8" is -10. AN line is done by sixteenths of an inch. So 8/16, is 1/2", 10/16 is 5/8", 6/16, or rather 3/8" is -6

Comes down to your choice. @565bbchevy‘s recommendation is the best bet if you can lose the trunk space.
If budget is a concern, the the Regal or FI Monte Carlo tank that ck80 recommemded with a either a Walrbo 450 or 525 in tank pump is good. If being the ultimate cheap and easiest serviceability, then add a $50 sump to a stock tank with an AEM 380 or Bosch 044 external pump. The external pump is a noisy gig if you have a quiet exhaust. But, dang, is it easy to work on.
I run the external gig with 2 AEM 380’s, but that’s me. Alot of folks don’t like the
Noise, but my exhaust is loud enough that I can’t hear the pumps once the car fires up.I can easily tell if the pump(s) are running though when they prime.

You won't flow 1000hp through a stock style hat. The oem 3/8 hardline outlet is too small for anything past a single 525. Twin 525's each with a -6 outlet and upgraded wiring is about the max for in tank traditional electric. The problem is the return is too small to run them continuously both on so you need to stage the second pump.
I crammed twin 450's in my stock tank but it took a lot of effort. I'm not sure if twin 525's will do 1000 wheel on e85 comfortably. Depends on the boost I guess.

No room for a fuel level sender I assume? Do you just keep the tank topped off?

I'm a big fan of surge tanks. It's surprising its not used so much on domestic stuff but I seen them used a lot on high horse power imports.
I currently have a Racetronix sender with their 255pump as its enough for my N/A setup. I later plan to add a surge tank in the location of the spare tire well.
I can also mention its seems a lot of people think you need a huge fuel line there is plenty 1000+hp cars running on -8 with no problem, even with E85. The main problem is not starving the inlet of the pump.
