4 barrel help 225 slant 6 offenhauser intake

Hello,

I am currently in the process of putting my 4 barrel intake on as my engine is now broken in since being machined out.

I have the Offenhauser 4 barrel intake , Its missing the 4 barrel carb intake plate and screws, , I also need the right carb I should go with ( 390 holley cfm) electric choke? I ordered the offenhauser #5270a bracket from summit, I am also in need of a new throttle cable as my currently one is wasted, what else do I need to make this installation a breeze? all help in direction to parts appreciated.

the engine was machined out .40 over oversized pistons, valve job, custom ground cam, head work, I had the engine machined out for the 4 barrel purposely , also has hooker super comp headers 2.25 exhaust , 8 3/4 rear end 8:55 suregrip, 904 torqueflite.

all help appreciated,

Thank you and God Bless :burnout:
