Come this january car will be 25 years old. And it will qualify for Texas classic or antique registration. Classic still requires a safety inspection but you are not required to have anything that was not "factory installed" that being the law you can remove the black box, Catalyst, o2 sensor, egr, and put the car back into eurospecification legally and drive it every day. If you only plan on using it on weekends then you can do the above and register it as an antique and you never have to do a safety or emission inspection. I don't know what the spec is for a 380 engine is but 16 degrees btdc is really retarded I assume for emissions and gas. Remove the epa junk and advance the timing and bring car back to life. BTW run 93 Octane if you do.
