Dry sumping

[FOT Fast]

Can someone please give me advice as to how I go about dry sumping a Ford 302 engine….where do I start?

My main question is how do I work out how many stage pump I need? Is a 6 litre catch tank going to be enough? What else do I need to consider? Etc, etc......

Thanks in advance.

Thanks for the insight everyone! I think I'll have to get the sump from the US but I was thinking about trying these guys for the pump:
