I'm running a non-EGR intakes on both of my 79 360s, one is FI, the other is carb. My 79 stock AMC 304 has the EGR valve.

So, I scanned the brochure to have a better readability:





Here is the EGR CTO Test from the FSM:



I would assume that running a different temperature thermostat than 195
could result in wrong test results...
