Have a four row copper brass cooling the 502....no issues...got a HD copper brass in 78..has A/C....again,no cooling issues...
Both have stock clutch fans...
You would gain about 25% more cooling efficiency with an aluminum rad....

4 core copper brass rads are actually 2 2 core rads put together. Any mismatch of fin alingnment means reduced air flow.
A 3 inch 2 core aluminum rad is one piece and all fins align meaning better air flow.
The generic aluminum rad fits out cars fine, you don't need the proper vet rad since only the lower rad hose outlet changes for the vet and that costs alot of money.
I just fiddle a bit with the lower rad hose, the upper fit fine.

A general fit rad has a straight outlet and the corvette one is angled up. YOU pay dearly for that angle up outlet. I just made up my own lower rad hose and saved hundreds.

Aluminum Radiator
norval, I'd be interested in seeing how you made your lower radiator hose? I am needing to replace my radiator and was planning on a copper/brass replacement due to cost of vette specific aluminum radiators.

I have a brand new in box universal chevy Northern aluminum 2 row 19 x 31 I bought for a C3 project that didn't materialize ... I've put several in C3 by fiddling w/ lower outlet/hose. Real nice rad ... billet filler neck & no epoxy. FYI, speedway's Tru-Kool P/N 917347-31 is this identical rad & they get $180 for it ... speedway tru-kool is made by Northern and if you get one it'll have Northern stamped right into tank. http://www.speedwaymotors.com/xq/asp...qx/Product.htm . Summit used to sell Nothern as their house brand ... maybe still do. I'll sell mine for $10 under cheapest verifiable price you find elsewhere.

Never had a problem over the years. Other then the 90 degree bend the rad fit like a stocker.
I also happen to use an original brass/copper radiator with great success on my mildly hopped up 72. However, my clutch fan wasn't working so well, so I replaced it with a flex fan (I was in grad school at the time, and money was tight). Thinking about electric fans, but have other higher priorities.

So was the 90 deg. elbow was attached very close to the rad? Like almost butted up against with a very short section of rad hose?

tranny coolers.......
Jackson, since this radiator doesn't have the tranny cooler, what would you, or anyone else, suggest for size of aftermarket cooler?
Looks like B&M has a 16,000 GVW, 19,000 GVW and a 24,000 GVW cooler......

That's what I was thinking, but I wasn't sure, since the only tranny cooler installation suggested using the original rad cooler in conjunction with the additional cooler.
I've learned something new, thanks for your advice!!! Plus the rad/cooler tips in this thread are going to save me about $300
