I dunno. I think we compared all that the first time you posted? It's all there in my EM garage listing.
Emissions DON'T mean nothing. Put the air pump belt on and log fe. Take it off and log fe. Bet you can't tell the difference. Emission controls are now pretty integral with the programming of the entire engine function. They work and I'm not aware of air pumps or cats consuming noticeable- barely parasitic- amounts of power or causing any fe drop vs not having them. Pre-efi emission controls were not as good, and they were a new thing for mechanics/home repair guys to deal with, and those guys did not like new, complicated, fussy things.
More on stat temps: the guys that want colder stats are the ones using their stock engine's work capacity near the upper limit- hard work, hot outside temps, and/or modified engines. Engines modded for more power generate more heat; too much more heat and cooling becomes an issue. Our problem is opposite: we are underutilizing our engines and they loaf along too cold for optimal fe.
