GM Crate 350 Ram Jet PFI Question

[Kuhlryde]

Hello. My first post here! Woohoo!

Does anyone know what GM means when they say that their 350 Ram Jet PFI engine has "a state-of-the-art injection system"? They don't give any details on it really. I would be interested in finding out exactly what they mean.

Welcome.

I'm really not up on that setup, I'm sure someone here knows a lot more than I do. PFI is Port Fuel Injection and I believe it can now run in a closed loop mode.
