I'm pretty curious about that flex-a-lite 295 setup myself. I currently have the factory brass HD radiator on my 69 bird with a flex fan. I don't overheat, but I specifically stay away from stop and go traffic.
Like others here on the highway it runs about 195 on a 90 degree day. That's at 3400rpm cruise. Cruising around the city at around 30-45 mph the temp drops to about 190, but as soon as you start sitting and idling temps creep and I've seen as high as 215 idling to get into a car show.
It seams like I possibly have two issues at play. 1. the factory rad probably needs a re-core (or a new rad) and 2. I have airflow or coolant flow issues at idle/low speed. The car is originally an AC car so it does have the lower and upper baffling, all of which is installed.
Wondering if the flex-a-lite 295 may help cool a bit better at low speed.
