[Tigers] Tiger overheating

[e.coiner at cox.net]

My Tiger overheating experience is directly opposite of the hypothesis proposed below.

I have told this story to the list several times about 3 years ago so I will deliver the Reader's Digest Version today.

Purchased the Tiger in Oct 2001. I immediately experienced overheating trouble. It would puke coolant on the garage floor after drives, it would peg the needle on the gauge when driving up steep hils at speed. The needle would climb when sitting in traffic.

I replaced a blown head gasket. 
I replaced the radiator with the one Rob Guerra sells.
I installed a Derale aluminum rigid blade fan that moves a huge amount of air. (I have a fiberglass LAT hood, If I rev the engine the corners of the hood will flex up to let the air out!!!)
I installed horn blockoff plates and the air scoop that Steve Laifman documented on the Tigers United website.

At this point the car no longer puked coolant after a drive, but  the temps would rise out of control when climbing steep hills or driving fast.  The faster I drove, the hotter the car ran.

I made one last change.  I replaced the Ford water pump with an Edelbrock High flow pump.

Since that change the Tiger has never overheated.  It runs at 190-200 on the freeway, climbing hills and sitting at idle.

One hot summer day I started the car in the garage (door open!) and let it idle for 1 hour.  The air temp in the garage was 104F the water temp was 205 F.  and stable.
Added a thermocouple to a port on the drivers side tank of the radiator so I know my temps are accurate.
