Default Aftermarket radiator question ('58-'60)

Has anyone out there purchased and installed a "Optima core" radiator like this? If so, I'd like to hear your thoughts and results. thanks (click on link)

They are careful not to say what metal the lowest line radiators are made from. Then, they go into aluminum, copper, different centers, etc.

I want to see the real numbers. Heat exchangers can be accurately measured regarding BTU/minute ratings. An important factor is, how easily air flows through the cores. Sometimes too many 'obstructions' slows air flow like a brick wall.

Keep in mind, when Squarebirds left the factory they were equipped to tackle the Mojave desert while running A/C. So, 'factory' is usually good enough for stock engines.

If you are serious about cooling your engine, get an oil cooler because oil reaches temps of 300-degrees F.

One way or another, my car is going to run cooler this year.

These old cars usually overheated due to excessive idling or stuck in traffic. An electric fan is the fix for that.

tried that already. I could idle all day with the electric fan, but temps would climb running down the interstate at 70mph. My engine also makes twice the HP than before. I went to a 6-blade fan with a proper shroud. I'm ok now unless its a warm day.

I have an AC car and the problem is low speeds or idle. The needle goes right up to the H, but not beyond. I heard the aftermarket fan shroud helps these situations. I heard this was a late 1960 addition. Is any of this confirmed? I'm aware Chevrolet eliminated oil coolers on the C5 corvette by mandating synthetic Mobil 1.

There is a fan shroud shown in the parts manual however I've had a number of '60's with A/C and none have had one.

My fan doesn't even turn on when I'm on the highway.

then perhaps my original radiator is not as clean inside as I am assuming.
