working on an 82 spirit was a 6 cyl, im converting to 8.
assuming the computer wont work with the 8 cylinder, and id like it gone and all the related wiring anyway. is this doable without making a completely new harness ? Im also going with a HEI distributor.

Very easy with an HEI. I have a DUI HEI in my Spirit and you just need a hot wire from the ignition key and your done. I have another DUI I ran for 20 years and keep it as a spare only because the new one has a built in rev limiter. Only problem with HEI is it is tight against the power steering pump. Im running a manual setup so no issue

It's an Ignition Control Module (ICM) and not a computer. The I6 and V8 used the same module.
Being in Ontario, you may want to consider using the Ford type Duralast distributor that would be original to that V8, An MSD6 box and the MSD connector for the distributor. PO is they are better. The other point being that Ontario has gone down the road that Emissions are part of Certification now. You need to be able to convince them that your "modifications" meet the emission standards of the vehicle, if you have not done so already. The Duralast distributor is original to the year of V8 and will connect to the original ICM. You would also need catalytic converter, EGR and the thermal vacuum controls for distributor and EGR. A TSM for a 79 AMX would be a great benefit. Also a new emissions sticker for a 79 AMX V8 for under the hood to replace the one from the I6. Good luck.

You mean you can’t slip the no fun police a 50 to put an emissions sticker on your car up there? Was doing that in philly for many years like every other hot rodder Ok maybe the OP needs to buy a vacation home here in Florida where we don’t have that revenue racket going on and move the car. No salt on the roads and drive it 365 hassle free

Not sure where your from but the e testing was cancelled a year or two ago. Its already certified.

Yes emissions testing was cancelled for non commercial vehicles in Ontario. But regulations changed for Certification of vehicles:
In this you can read that a passenger vehicle must meet the requirements of NSC Standard 11: And in this you get the following: "Requirements Vary- The emission control devices
and system required on any particular vehicle will
vary based on the vehicle’s date of manufacture.
Possible Roadside Violation - In some
jurisdictions a vehicle will fail an inspection if the
vehicle is not equipped with either a National
Emissions Mark (Canada) or U.S. Emissions
Control Information Label. If the emission label is
not present, advise vehicle owner that the vehicle
may violate a roadside inspection requirement
based on jurisdictional regulation. Further
questions or issues are to be directed to the relevant
jurisdictional authorities." The new training program has 1974 being the year that the emissions label and systems are to be inspected and installed as per year of manufacturer. As stated, good luck. Right now they are behind and for the most part "allowing" some modifications. When everything goes digital in 2023, what the emissions label for the vehicle states is what has to be installed and working to get a vehicle Certified.
