FiTech EFI system

Seriously considering doing this in late June for my 520 hp 408 stroker. Tired of having it warm up for 5 minutes and mpg isn't the best depending on how hot or cold it is outside. Thinking about the following the Easy Street (P/N 30005 - FiTech Easy Street 600 HP Self-Tuning Fuel Injection Systems 30005). I don't need all of the special features, just basic fuel injection. I currently have a stock gas tank with a Holley Blue external fuel pump and an MSD Ready-to-Run distributor. I've been drooling over FiTech ever since they came out.

Ideally, I'd like to go to a Tanks Inc with a fuel pump in the tank, but I'm not sure I have the funds to do so.
