I was going to swap a 351 from a old project into a 1998 3.8 Mustang. Just realized the state I am moving to has emissions testing. Is there a way to pass? The 1999 Ford Explorer had odb2 and a 5.0 but not sure if the Mustang firing order will work with that computer. Should I just start looking for a 1994 / 1995 Mustang. Cars older than 1995 are exempt in that state.

. it'll be way cheaper and a lot easier to get a 94-95 5.0. You'll need an ecu, wiring harness, sub frame and figure out the fuel lines. I think the fuel system is not the same. And then keep it registered out of state of find some one to smog it for you under the table. Or just get a 94 and F smog laws.
