About 600 miles on the engine. Running stock cooling system for 1973 Dodge Dart Sport 340 with what I believe the original radiator 26" with stock shroud and 18" 7-blade fan with thermal fan clutch 13lb cap and has A/C but not working at the moment. System has been flushed once during heater core replacement last year. Engine was installed late 2016. Timing is initial 12" with about 32" total. A/F set via drop rpm method with the highest vacuum 14". Idles at about 800-830 rpm and runs good otherwise, but seems to run hot in Sunday morning minimal traffic, 85-90 degrees. Seems to idle for 30 min. in driveway at about 205*
Here are the specs per my MRL build sheet:
Edelbrock 1406 600 CFM carb with step 23 setup
Airgap type dual plane intake
2.02 Intake valves

Radiator hoses are new gates, but lower one does not have a spring in it.
Used ifrared temp reader and temp is about 13* difference from top of raditor by hose inlet to outlet.
This seems to run hot y/n? What are my options? Water Wetter?
Thanks.
