I was going to ask about the weight difference but
then thought that it wouldn't be that much of a net
gain to be concerned about.
Seems like a reasonable alternative as a solution
for OEM C4 cooling. I do not follow pricing but I'm
guessing this one is at or toward the bottom end
of the price range.
What were the circumstances with the test mule that
led to development and what kind of results were
observed?

Test mule was my ex-wifes 89. L-98, 383 stroker, 10.5:1 compression, Reed custom ground camshaft, 180* Robert Shaw thermostat, and custom PROM, 3" stainless exhaust with pre-cats removed.
This was and still is her daily driver in Atlanta traffic. Forget running the air as temps would easily reach 240* and climbing in heavy traffic. 190-200 deg on open road. This was with a new TCI radiator 1 3/8" core. (TCI manufactures OE cores for AC delco.)
With the 10.5:1 compression at these temps you would get detonation under load which causes the computer to retard timing drastically. Subtract about 100hp when this happens.
With the Extreme 3-row, average tempurature drop is about 15 degrees over stock on open road and temps are kept in check in heavy traffic with the air on. 210-220 vs. 240 and climbing.
Open road 75* day with a 180* stat, air off, it often will not reach 180*
Hope this helps,
Doug

The factory radiators are marginal at best. To give you an example, the Ford focus with a 2.0L 4cyl. uses the exact same core dimensions as the 84-89 Corvette with more than double the dispacement. They also use dual 12" fans staggered ,1 high 1 low in a shroud to fit the 23 5/8" core. They move a tremendous amount of air and can be used on the corvette if you are in a fabricating mood. I have had a customer that did this modification with great results.
We have also used this radiator and fan setup on a tube chassis rock crawler running a 5.7L hemi. due to limited space on the chassis design.
This is a low speed, high torque application with minimal air flow and grill opening.
Here is a link to the rig and shop that built it if you are curious as to what I am talking about.

It is about design. Our's uses two rows of one inch wide tubes and measures 2.25" thick. (2 x 1= 2") vs (3x .5= 1.5")C. The forum requires sponsorship to post sales links (moderators?)

Not product bashing. 
Just giving options other than all aluminum.
Our cores are 1 7/8" overall thickness. They are a high efficiency design
with a high tube and fin count. This is just as important if not more than important than core thickness. Older designs from the 60's and 70's used 2 1/2" and 2 5/8" cores but used low fin counts 10-12 fins per inch and 1/2" or 5/8" tube spacing. The extra core thickness was needed to compensate for the poor efficiency of the core design.
Either one of our products will do an exceptional job of cooling,
providing that the rest of the cooling system is healthy and there is adequate air flow through the core.
There are a number of products on the market called high performance.....some work, and some don't.
Our products work. We pride ourselves on our product quality and value, and our customer service cannot be beat.
If you have a cooling issue, feel free to give us a call and we'll do our best to point you in the right direction. A new radiator isn't always the solution to a cooling problem.

That's fine, but what Tom is pointing out is that the Forum requires sponsorship to post sales links... do you plan on being a supporting vendor to the Forum? If not, I suggest you remove the links.

Sorry if I came across wrong. I was genuine in my reply and understand your logic completely. 
I frequent several boards on 4 wheeling sites, which is my passion, just like corvettes on this one. It is just common sense to look at a stranger with a bit of apprehension when they show up pedalling snake oil.
I do have first hand C-4 vette cooling experience as well as most other vehicles in general. That is all we do.
Our advertising guy is working on a sponsored add so that hopefully we can all help each other in the future.
Hope to talk to you again.
