I'm looking for a radiator and I would like some feedback on the options out there.

First though, I am going to be running Evans NPG+, and they recommend 1-1/4" tubes in the radiator. I have only found one company (Griffin) that has this. Also, I'd like to run a built-in radiator cooler.

Now, I have found two radiators that fit my requirements, they are the 1-55272-T and the 6-570AE-BAX. The first one is a "Circle track" radiator and the second is a "direct fit". The direct fit version is much more expensive, but I don't know why. What are the differences?


TIA!

What are you running that you think you need this much cooling? A stock 4 core radiator keeps my BBC at 180° all day.

This one works well, and its a DROP-IN Replacement with NO Modifications needed. They are about $100-$130 at the Parts store.

I'm supposed to be getting 500-550 hp, and NPG+ is thicker than water/antifreeze, so it needs the larger tubes for best performance, according to Evans.

Unless you're running forced induction I wouldn't worry about it too much. I was going to try that Evans cooling years ago, but at $20/gal I decided against it. A good AL rad like above should work well.

Please consider one of Summit's house brand aluminum rad's from Northern Aluminum Rad.

i have one in my 1st Gen. car now! Good value to me if you don't mind a little fab. work.

You really don't need to go through all that to cool the motor. Any decent drop in two row 1" tube aluminum radiator with standard antifreeze will work just fine. Lots of us are running much more power with this type of setup on the street with no issues at all.

Thats what I have. Really nice and when I got it it was only about $160. Didn't take any work to make it fit. And that thing is HUGE.

+1 in hhotts rad, I have the same one, and cooling has never been a problem.

The Griffin Radiators work very well and for less than $200 is a great investment. With electric fans I never get higher than 200, EVER! Just measure twice, but the brackets and fit the biggest one you can in there! :)

Make that +2, I too have the same rad and it is literally a drop in piece. This summer has been hotter than hell, and no cooling issues at all.

Rick, you are absolutely correct, I don't need to go through all that.
It's just that I have got it into my head that I want to run NPG. It has a few advantages over regular antifreeze and can allow the engine to be more efficient, if you tune it to take advantage of the differences.

Yes, it's making things more difficult for me, but it's just one of those things that I've just decided I've got to go with.

Whats NPG?

All the good reviews on the rad that transpro makes made me go out and buy one to put in front of my 434 sb. I hope to give some good reviews as well. :cool:

NPG is a Non-aqueous Propylene Glycol. It is an antifreeze/coolant that does not use any water. See this link for the website and more info: http://evanscooling.com/main25.htm

The NPG and NPG+ are "lifetime" coolants. Because they don't use water they don't cause corrosion, and don't break down.
They also have a racing product that has a different formula (NPG-R) that does need to be replaced periodically.
