Curious what other 426 strokers temps are in 90 degree weather with 185 thermostat with the ac off and ac on. Mine with the ac full blast is the little white line before 215 and with the ac off 200 degrees
AC off I’m usually at 191-197, with AC on I’m usually 203 - 220 depending on driving. Local streets it sits about 203 but on the highway doing 80 it’s about 220 per the trinity ECT readings I keep up at all times.
I am supercharged with the Karma racing radiator and it doesn’t seem to matter much temp wise.
