I have two Proms and need to identify the one I am holding in my hand. It's an ACXS1088. Is this from a 305 or 350 car? Also, the car I currently have is a 350, but has 30lb/hr injectors. I'm assuming I'll need the injector constant changed on a stock PROM? What kind of problems would I face if I attempted to run the vehicle short-term with a stock PROM and 30lb/hr injectors?

Thanks.
