And in simple terms - if the coolant goes through the system too fast it doesn't have time to cool down, so if the pump flows too much we'd be running nothing but hot coolant.
I have the same problem with my 64.5 Mustang. I put 3:55 gears in the pumpkin and at highway speeds I've been have trouble with it getting hot ever since, it's running around 2,950 RPM @ 60 MPH. I finally figured out that it's just pumping the coolant through the radiator so fast it don't have time to cool. I just ordered a complete 3:25 posi unit for it last week. I wanted 3:40 gears when I changed them out a few years ago, but was having trouble finding them and just setteled for the 3:55's.
