Tuning in an Older Swapped Truck

I'm not sure how your laws are but in California whatever is newer of the engine or chassis is what the smog regulations are based on. as the engine is newer then the chassis the emissions regulations would be based on that. how does your state deal with that?
To be honest I'm not sure in Az, I need to look into it further. I would have to think most states will be more relaxed then California.
Per the fed's and EPA, since it came out of a VIN'ed vehicle, it needs to follow federal emssion standards for the year of truck. So regardless of what AZ says, its still a federal problem and why its no easier to find tuning for it
that's what I was afraid of. Now for the guys that are truly off-road only are they having trouble getting around the fed's VIN'ed rule?
yup. there is no such thing. you have to use an engine block that is not vin'ed or out of a vehcile (basically a custom block like a wagler billet block) and the chassis must never have been vin'ed from the factory (like a tube chassis or home built frame and cab). In those cases, the EPA has no issue. if not, it will run into issues.
You as a regular dude most likely have no worry. they have bigger fish to fry than you. But from a tuner stand point and shop stand point, that is the problem
We’ve swapped a bunch of vehicles throughout the years. All old school, 60’s, 50’s and 70’s. No issues with inspections or epa or etc. from all over the country. Most in cali.
You won’t have an issue, roll with it.
