I am considering a V8 Fiero to be registered in Wisconsin. What are the rules? The info I can obtain from the Wisconsin government sites doesn't seem to know about engine swaps.

I may not be a lot of help, but I don't think they care or will ask what engine is in it. They should just need the vin make model and color.

Fieros are too old for emissions testing based on this site, which is where things would get difficult if they did:

The other thing you could do is call your local WI DMV and flat out ask a hypothetical, what is required for registering a 198X Pontiac (that maybe you just bought?) in your name.

I'm not searching for you state partly because some states have charge rules in last few years.
Some notes:
dmv.org is ok but don't trust them for important data.
Some data is on State DMV site but isn't full text in State Laws or Regs. Look for State Code site for full text.

Recently Some states or counties/city have dropped emissions testing for 25+ year old cars OR cars built before OBD2 but you need to check local rules/laws because Other places still require E testing back to ~1975.
More confusing, Some counties/cities require E testing but rest of state never did. Goes by address/zip on car's registration.

Most states w/ inspections never cared about engine used in vehicles w/ ODB1 and earlier but must pass Sniffer and EVAP (if car like Fiero has EVAP equipment) tests. Not like CA residents dealing w/ CARB certs etc for all swaps.

Not exactly a smog expert, but live here and know a bit.
I am over in Walworth county, and we have no smog at all here.

You should hear and see some of the pickups around here.
Engine swaps galore, loud exhausts, etc.
I usually expect to see a high performance car when I hear them coming, but nope, all modified pickups.

Here is a copy and paste right from the official Wisconsin DMV web page.....

"Which vehicles require a test?​

The Wisconsin Department of Transportation (WisDOT) notifies vehicle owners when an emissions test is required. A test is required when license plates are renewed (the renewal notice contains details) and when ownership changes (a letter is sent).

Vehicles require an emissions test based on:

Vehicle location
Vehicles customarily kept in one of the seven southeastern Wisconsin counties of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington and Waukesha.
Certain vehicles
Autos and light trucks model years 1996 to 2006 that have a gross vehicle rating up to 8,500 pounds, not including diesel powered vehicles.
Autos and light trucks model years 2007 and newer which have a gross vehicle rating up to 14,000 pounds, including diesel powered vehicles.
Certain regular occasions
After a transfer of ownership (transfer of plates or new plates issued).
After first registering in Wisconsin.
Before renewing registration (biennial testing, see below for details).
Certain non-regular occasions
When identified as having tampered emissions equipment.
When identified with fraudulent vehicle location information.
Government vehicles when designated by the department.

Exempt vehicles

The following vehicles are exempt from emissions requirements (except for vehicles identified as having tampered emissions equipment):

Model year 1995 and older vehicles.
Model year 1996 and newer vehicles that are not OBDII-compliant (must be verified at a test station).
Diesel powered vehicles with a model year 2006 and older."

Only Sheboygan area, Milwaukee area and Madison areas have smog, the rest of us ignore the commie bastards and live free smoking down the road in glee Merica the hell out of it as ya please!!!
