They make a 2 into one fuel line that hooks to the carb so you can run the stock line from the pump. Other then that all you need is a few vac plugs 
Thank you for the advice everyone! I looked at a Holley 650 DP for the 401. What else besides the carb would I need to hook it up? I am the amatuer with this so please be patient. It has dual line feeds, so I assume I would need a splitter from the fuel pump? If I have 1/8 NPT fittings on it, what else would I need? I don't know, so please school me.
