How to break in a new fuel injected engine?

The stock ECU is gonna be scratching its head over the MAP as your new cam will be pulling ~12" instead of >19" so it will be dumping fuel. making it rich. Your O2 will be like WTF and will be cutting fuel to clean it up. its a vicious cycle...Id run a stock jetted carb with nothing but the ignition hooked up for the cam break in. The 'running the motor like you want to drive it' would pertain to a learning ECU like an EECIV or something a little more flexible than a Mopar ECU. If you dont have that option. get it to start and run to 2000 RPM, and hold it there while watching your AFR. It may be enough RPM to get the ECU to play nice and give it an acceptable afr. If your running a roller, then dont worry about cam, worry about your ECU keeping up with the strange demands of a non stock cam. MS it!

Cam will be a full roller,seems strange to want to even consider a flat tappet cam when the engine comes stock with a roller cam. I watched an episode of engine master's back when it was free and they were comparing carbed and fuel injected engines and they couldnt get the fuel injected engine to run on a carb manifold because the vacuum signals were weird so they put a single plane intake on it,and it ran fine. I'm kinda interested in the stock cheby ls engine management because supposedly its pretty adjustable and swap friendly.Eventually ,I would like to get rid of the distributor and run a coil near plug ignition system for the hotter and more precise spark.That is a lofty goal but I should probally take it all in stages rather than building it like that first because then it will never get done..
