Fi and cast iron heads

Yes it has two available ports for PCV and one for engine vacuumed off throttle and on. Dependent on if you need a port at idle vacuumed or open throttle vacuum.

The FI tech fits both throttle openings with no adapter. One thing I’ve noticed is if you buy the lower level unit it’s $799 but limited tuning. Has provisions for electric fan control and ac kick up at idle.

The people who have the YouTube videos who complain about the system all seem to be Mustang owners. Lol! Anyhow. FI Tech tech assist does suck. And when they do pick up the phone they act like you are bothering them. - my first hand experience.
Also a lot of issues with that adapter fuel pump can they sell. I went with a new tank with the pump in the tank from Tanks Inc.
Told them what I was building and what it was for and CC over the phone and tank, pump and sender for my 66’ Barracuda was at my door in no time.

Also if running in an early abody... you need to drop the air cleaner. I modified a 273 air cleaner and a cheap base from Jegs to fit.
