Crossfire Fuel Injection

Hi I got a 1982 Camaro Z28 with the crossfire injection and the engine is bad, it is a 305 Sb and I want to use the crossfire on a 400 Sb truck engine. What problems will i run in to?

Many, also known as the "cease fire injection" these were not used for very long for good reason, and they are, Extremely poor fuel distribution, ports less than half the size of the head ports so the engine runs out of breath very quickly due to insufficient air flow. These systems choked a 305 to death, god only knows what it would do to a 400.

It's more like, "What problems WON'T you run into?" They didn't work right when new, anybody I knew with one ripped it off and replaced it with a 4 Bbl. or sold the car CHEAP......... Bad news.

Ditch the CFI and go either carb or TPI (or later if you can afford it). CFI aren't worth the time or money to make them reliable and efficient. They came on the Corvettes for 1 year . . . what does that tell you?

Wasn't there an aftermarket intake offered for this setup at one time? I was doing a lot of TPI and ROCHESTER feedback carb work many years ago and was impressed by this setup.

I have since recovered from the experience (intervention and/or exorcism) and been GM free for some years...
