No real 'code'. They are all black, made by Bosch, and have the Bosch part number 0-280-150-218.

Can I damage a stock engine if I drive it on 50 lb/hr injectors?

Not if you have a chip that is caibrated for those injectors.

The Rochester / MSD 50 lb/hr injectors are still high impedance, and compatible with the stock ECM's injectors drivers. I have driven a car using those injectors. Th eonly caution is that the may lock up under high fuel pressures.

Low inpedance injectors need modifications to be made to the ECM. (i.e. low impedance drivers to be installed)
