Why not just go aluminum for about the same price?

Find me a 4 row aluminum that will fit without issue for under $250, then.

Heh the original is 25 years old. I would think ANYTHING new would be able to beat the original.

Will it fit? That's the big question.

Summit, Jeg's, etc...my local speedshop for $179. I then took it to a local radiator shop along with mine for a pattern and the rad. shop ordered a couple of aluminum necks and for $35 walla! It fits perfectly. It is 2 rows of 1" aluminum tubes. Make sure you get the fully welded one. No epoxy.

If the original was 3400 BTU and the "new" one is 3200 BTU then your going to fight to keep it cool.

I replaced mine with a Silla radiator, it fit perfectly and I have no cooling issues with it. I bought it off Ebay for $150. and free shipping.

2 rows? The original is a 4 row, how can a 2 row aluminum radiator be more efficient than a 4 row copper/bronze?

Maybe a radiator expert can chime in here for me and explain why aluminum radiators cool better than copper/bronze ones. My experience with cooling is mainly with computers and the best cooling for CPUs is with copper. Copper has better heat transfer but takes a little more flow to keep it cool, while aluminum is quicker to cool off, but doesn't transfer heat as well. Silver is the fastest heat transferer but due to cost isn't really any benefit over copper.

My copper/brass radiator did a good job cooling. When it sprung too many leaks to fix, I went with aluminum. It was very impressive how it would now just sit on 180 all day long no matter what.

Makes pretty good sense. Can't make the tubes on a copper/brass radiator as wide due to weight. So they just use a bunch of small ones.

On there it mentions visteon only makes aluminum radiators. A visteon radiator at kragen is only $244... However there are no specs listed.

A 2 row radiator has bigger tubes in it's cores...I believe the c/b uses a tube which is 3/8"--so 4 x .375=1.5"...........and the alum. radiator uses tubes which are 1"--so 2x1"=2"......................Also I believe c/b has a fin height of 1/2" as apposed to 3/8" for aluminum giving u more levels in it's core.....plus look at the C6-ZO6..GMinstalled a single row alum. to cool this bad boy.........

Be careful with the cheap Chinese copper/brass radiators. If you look in them through the radiator cap hole, you'll notice that the internal welds are so bad that the coolant channels are almost half-filled with solder.

The Summit-brand aluminum radiator is made by Northern. Very nice piece of work, fully welded. Some speed shops might also have them - I got mine for a good price at a swap meet from a semi-local speed shop.

if it fits perfectly as an above poster pointed out thats a pretty good deal.

The issue I always want to know is if its fits perfectly. YOu dont want to mess around with it for hours trying to get it to work. The cooling capacity is important too but if you aren't running anything with a ton of HP it won't be a huge deal.

Just as a side note, my alum cools much better than the original but its also WAAYYY lighter. The original copper brass are pretty heavy.

Quick note, I read some old forum posts about how some of the universal Aluminum radiators from like Northern fit without modification. Can anyone elaborate on this? If I can get a universal aluminum that will fit fine I'll take it.

I'm sorry about the attitude, but it just amazes me how some Corvette owners can drop 5k into building engines and then become squeaky tight about cooling it down. There was a day when Corvette people wanted the best for there car, not the cheapest thing they could find.
