That's why I made a thread! There's hundreds of threads but I don't have time to look through them all. I work on the road and when I get home I'd like to have all my parts ready to install.
I've got most everything already, just need to find a fuel pump and some exhaust.

At that level I would do a dual pump setup personally. Dual walbro 400s at least with 80lb injectors and -8an feed and -6an return. Should be good to an easy 850rwhp on pump gas and will support 30psi of boost.

You don't have time to read, yet expect to make an 800 hp 5.3 live. Good luck with that.

To answer your question, 1 or 2 walbro 450s, aftermarket fuel regulator of your choice located after the fuel rails, and 80 lb injectors. -8 feed line and - 6 return.

If you stick to just 1 pump you should be able to make the Walbro fit the factory sender. Will take some hacking but I don't see why it couldn't happen. It's similarly-shaped, but not the same - but the old style sender is a wide-open little skeleton that you can hack.
