Engine too cold when cruising at speed?
My 69 302 has all Edelbrock Performer RPM parts and a big horizontal flow aluminium radiator with twin electric fans. Overheating is not a problem and it all behaves itself just fine when cruising around the town showing 1/2 on the temperature gauge and when stuck in a lot of traffic it can creep to 2/3 on the gauge.
But, I have recently done a few long drives on faster roads of about 60 - 70 MPH and have noticed the gauge can drop down to about 1/4 on the scale. I assume this is from the airflow through the radiator at this faster speed. I have a 5 speed manual gearbox and in top gear, I am barely touching the throttle to achieve 60 - 70 MPH. Is this lower temperature a problem or quite normal? I cannot remember what the gauge did before all my modifications and my old 3 speed automatic gearbox. The car drives just fine and this is just a query. As soon as I get back to town driving speed or traffic, then the gauge increases to the more normal temperatures above.
