To be honest and don’t take it the wrong way ok, if you really don’t have any jest on these things believe me they are not plug and play as Holley states and all you will be doing is pulling your hair out running into issues . I’m not sure the 6 A box will cut it if you want to run the timing as well as I think they are the analog type some one will correct me if I’m wrong. You can use it as a stand alone unit without the timing control. The master kit with inline pump are junk better to run in-tank pump. When their on and running correctly they are awesome , easy to tune via laptop as these are things you will need to do so if your half cocked stay with the carburettor and save your self pain and sufferings. Just my 2c
