Did they put a 2-core radiator on any small blocks on a 68? Will one work with a 350? Will the shroud for a 2-core fit a 3-core radiator?

The standard small block radiator was a 2 core.
The shroud will fit either a two or three core; the tanks are the same, just a different number of cores.

Air conditiong and/or high perf. dictated the larger radiator.

Rats, I'm building a healthy 350 to replace my 6 and eventually would like to add Vintage air. I guess I'll need a 3 core. I bought a used rad that I thought was going to be 3 core and it turned out to be another 2 core not even as good as the one I have. I wonder if I can splice them together

Big block radiators are a couple of inches wider, so a 3 core should work fine. Even a 3 core small block, in good condition, should be okay.

If you are starting from scratch..and depending on how much hp and climate you are in, I would go for an aluminum crossflow for your application. A three row is questionable, depending on application in my opinion.

More on cooling at www.inccn.net/techforum.htm at my cooling tips page.
