1965 Barracuda Radiator Help

I used the same radiator but had to make a fiberglass shroud for it because there is so little room under the hood there is little space for air to blow. The fan didn't draw through the radiator, even when spaced very close, without the shroud.

So with the radiator I will have to have a shroud to go with it...also of course some sort of overflow can would I not?
