3 core radiator?

I posted this same thread on another forum, I'm not trying to disrespect anyone but the more opinions I get the better for me and my motor.
I really have no idea how to tell a 1 core from a 3 core. After looking hard at the radiator I have, I *think* it might be a 3 core. The whole core width is 1 7/8" and there are what look like 3 different tubes on the inside. Anyway, here is a photo, can anyone confirm or deny?
Thanks

Yes, that is what "3-core" or "3-row core" refers to. Easy to tell just by removing the cap and looking inside the tank at how many rows wide the core is.

Awesome, thanks guys!
I was worried. It came out of an El Camino with a 305 but my guess is at some point the previous owner put a better one in when he put the crate 350 in it. Now I know it should handle the stroker going in very soon.

I don't know if you should go off the deep end yet. It's ability to handle a stroker bigger than a 350 will depend on how well it flows which will have something to do with how clear the tubes are. It would be good to get it checked out by a shop that knows what they're doing as crud and corrosion collect in the tubes. Chemical cleaners are not very good, if it's cruddy it needs to have the tanks removed and the tubes rodded to remove debris. This is a lot cheaper than replacing a toasted motor 'cause you assumed the radiator was up to the task. It happens a lot.

If you ever have a radiator where yo can't see the tubes from outside, just open the cap and look down in the tank. Three rows of openings = a three core radiator
