AFAIK, you cannot use the Camaro cal to run a 6 cylinder engine, the firing events are not spaced the same, IE V8 fires every 45 degrees, and a 6 cylinder fires every 60 degrees, hence the firing events (both coil and injectors) will not fire at the correct time. You can use a V8 cal on any engine that fires every 45, 90,180, or 360 degrees(and a few oddball spacings that most engines will never use). Opens up the possibilities for injecting other engines..... HMMM I got a 5 HP Honda pushmower with carb problems........ '411 swap with coil on plug should work!!! THe only 6 cylinder that uses coil on plug that I am aware of(that uses a friendly computer) is the '08 on up 4.2 I6 in the Trailblazer with the E67 PCM. Hope this helps!!
