I also run a mild 351 in my XD ESP. I have a 3 core with standard thermostat and standard clutch fan and normal driving never sees the temp gauge make it to half way.
On a recent track day at Oran Park with the vac secondaries open most of the time it only reached half way after 5 hard laps.
So I think a 4 core would be a waste of money.
Go the ESP's!
The cop said "Do you know why I pulled you over". I said " Well, that all depends on how long you have been following me!"
