I'm pretty sure you have to change the computer as well. I was thinking of putting the crossfire onto the 350 that I have for and then found out just how much it would be to get new injectors and a computer.

For one you don't have to change the ECM (computer) but you will require a new Prom (chip) with updated for a 350. Also needed 65# FI , 350 knock sensor.
