I have the small passage 440 Source water pump housing on my 500 in. motor. Runs cool as a cucumber.
But whats the average temperature in Prospect, PA? Today in SoCal it hit 109 degrees..
Just my $0.02...
The average temp in Prospect Pa is not 109°F, nor is it in So Cal. The car runs fine in the low 90°s, but I prefer to not drive it when it is that hot.
