I bought a Aeromotive Stealth II tank with in-tank 340lph pump for my 70. I like the Stealth II tanks much better than Tanks Inc. (that's in my Chevelle), and it's few $$ cheaper.
-6AN supply and return, came pre assembled and ready to drop in.
Looks like the Tanks Inc. new style baffled EFI tank is the way to go!
Missed the recent tank thread so thanks for the fast heads up.
JMO but I think stealth II is the way to go. With tanks inc tank (new design, notched corners) on my chevelle I still get fuel starvation when its below half a tank. Especially on take off, by the time I grab 2nd it stumbles.
There is more info on Chevelle and pro touring forums regarding tanks.
I went with a RestoMod tank from Rick's Tanks which uses a late model fuel pump from a 5th gen LS3 Camaro (2010-2015). The Rick's tank does not have internal baffles, but the Camaro pump module has a siphon jet that pumps fuel into a "bucket" at the bottom of the pump body to prevent starvation. The operating pressure of the 5th gen Camaro pump is too high for most aftermarket EFI systems; the solution is to replace the 5th gen bypass "poppet" valve with one from from a 4th gen Camaro pump to reduce the pressure to 58psi. I bought a kit from a company called VaporWorx which included the 4th gen bypass valve and an electrical connector to power the pump and really clear instructions. VaporWorx told me the LS3 Camaro pump can support up to 400 HP. Another nice benefit of this set-up is the internal bypass valve in the fuel pump module will allow you use a single fuel supply line without the need for a return line (a "dead-head" system). This makes it much easier to retrofit EFI using the original factory fuel line. Here's some pics:

I tried going that route, I was planning on running PWM module from VaporWorx with my LS swap, however Rick's is completely sold out of Restomod tanks and no idea if they will bring them back. They were not selling that well, according to Rick's.
I've spent a lot of time on the phone with Rick's, Aeromotive, Tanks Inc. and Carl from VaporWorx, and many hours researching the net before I decided on Aeromotive Stealth II.
Tanks Inc baffling is not really good enough for any kind of "spirited" driving, especially if the level drops below half a tank, they will tell you that. Their 2nd design with baffling is improvement, but still not ideal.
Aeromotive Stealth II system seems like a much better design vs anything else available, unless you have $2k to burn on a custom tank.
The foam and bladder design will keep the pump submerged in fuel even when level is low.
Also at $578 (340 pump) it's cheaper vs competition.

I did as you, and called RIck and Carl to get advice for my fuel system. I really wanted to use the PWM capability of the FiTech EFI to minimize fuel heat-up but was told the Aeromotive pumps are not compatible with PWM. For those that may not know, the FiTech systems can be programmed to reduce the fuel pump speed at idle; this reduces the pump noise and unnecessary fuel recirculation which heats up the fuel.
Stampcile:
The Holley pump you linked to looks like a really easy conversion, but the pump is not PWM capable which means it's running full-speed, all the time. How loud is the pump?

It’s quiet. And like you said, easy. The car came with Summit brand in-line fuel pump and it was louder than the exhaust.
