Fi and cast iron heads

4EB7827D-9C7F-4442-9604-21BC81AD180C.jpeg Sorry no newer shots with electrical hooked up. I’ve got the fI tech on a 318 cast heads and Eddy LD340. Runs good.
Only issue to be concerned with BUT able to be corrected is you need a 3/8” pipe fitting for the coolant temp switch for the fuel injection. Also remember if you run electric fans with automatic start stop switch you need port for that as well as a factory 1/8” pipe for factory temp gauge.
