More Radiator questions

I have done a serch and have read many of your suggestions.

I went to my local rad guy and he said that he could take my rad from a slant 6 1975 duster and add a third line of tubing tawould be ok for my soon to be 360.

It occured to me that the inlet is perobably on the wrong side but someone said that could be relocated to the other side.

The car did not have a shroud when I go it.

I gather I should have either a pull or push fan with circuit that will turn it on at a specific temp..I think 180 was the number.

I should also go with a 180 degree thermostat as well..

All parts from summit ?

If I do go with another rad, I have a friend that is doing a body off resto...and yes, he did take the body off the frame..he said there there were chevy rads that will fit that you just have to drill holes..I have to anyway if I go with a bigger rad..anyone of this ?

Or if I buy a new rad, do any come woth a shroud ?

And is a shroud necessary with electric fans ?

Thanks
