Thanks for the replies Jon, Jerry & George. No George, not a joke.
Rad was just an impulse buy (I think $15) and I just shoved it in a corner. Tripped over it again and I thought I would start looking closer at it.
Now with all your advice ( I was slowly getting there too), I will get a a new V8 radiator with as many cores as I could find.

Just need to find a new proper 216 home for this radiator. Thx!
