Well you'll need a carb fuel pump

OR

You'll need a pressure regulator that has a return line.
The regulator will have to handle the pressure of the EFI pump and be able to bring the pressure down to 2.8 - 3.0 PSI

The EFI distributor can be used on the carb... keep as much parts as you can off the BT.

I'm not in the mindset to give you a full list of things you need.
