Let's be clear. Your 74 is NOT SMOG EXEMPT!!!https://460efiguys.com/ Was the site I was looking at.
I understand the concerns about "Legal" conversions etc... My bronco is a 74 registered in the C_____IST state of California and is smog exempt. Not once have I had the DMV or a Police Officer inspect it. For all they know I have a 2026 hybrid engine swapped from a Prius.
Your 74 is not required to be smog inspected. (not the same) The fact that you do not subject yourself to bi-annual self-incrimination does not mean that you are exempt from the laws. You are only exempt from the inspections.
If you get tagged as a "Excess smoking vehicle" and reported to air quality management, and you have money...you will get a visit.
The fact that they don't know you are breaking the law does not mean you are not breaking the law. Which is fine for an individual scofflaw. But it creates an insurmountable hurdle for business. This is why you can't find anyone selling performance chips, EGR delete, DEF delete etc without securing a CARB EO exemption and paying the individual State extortion fees.
It also creates a logistics nightmare for companies like Summit, Jegs, Etc. where they can't advertise products for sale on pollution controlled vehicles, so you have to lie to them to give them deny-ability. All of this is in violation of the Commerce Clause, and creates a de-facto interstate tariff. But until it gets past the 9th circuit it remains law. So there's that.
