It was intended for a first gen camaro.

I would like to buy one but don't know anything about aftermarket radiators. Can you please tell me why they are so different in size? I am building a 69 z/28 RS clone with a 427 small block and Vintage Air. I am sure one of these would be ideal but need some help on selection.

Thanks
