It used to be 180* before closed loop. It is on my 88 5.0 LX, but I guess that is the old EEC-IV ancient technology

I used to run a 160* in it for the summer but I also run the timing cranked to 15* N/A or at 10* with a 100hp shot of NOS

Today's engines are designed to run at 195 with no issues.

Heck, my 01 F150 5.4L I had ran fine in 98* weather, with the a/c on, towing 7500lbs. No pinging or anything. I even ran a Diablosport Predator on 93 octane.
