Rated at 550HP stock, turn the fuel pressure up from 43.5 to 65psi and you're good for 600HP, assuming you also go with the larger pump or swap in a walbro 255L HP (GSL392)

I run dual walbros and 80# injectors @ 60spi. TB is rated up to 930cfm, so my set up now can go much higher.

FAST has a new TB set up rated to 1200HP. I picked the PJIII since it had easy self learning but also the ability to unlock the programming and go in deep if you want. It is also the only stand alone TB system that is boost and nitrous ready out of the box. I run a 200HP nitrous hit at the track with my PJIII. Works great.
I was looking at another manufacturer but they said it would not work with my cam. I have a very hot cam. So the powerjection is really that easy to get the car set up and drivable?

Most EFI is a lot easier than tuning a carb and dstributor IMO.

If you can afford it going EFI is a no brainer- but its not a traditional look at all.

If you go that route you can use the entire harness, computer, engine, etc from a LS truck/car...

You can start to see why a boosted 5.3L is such a popular alternative- crazy power, crazy cheap, very easy to do.
