Can anyone tell me if Ford used a Holley 94 carb stamped ECG on one side and script Ford on the other on a 239 Y Block in 1954? My research points me to '55 for the first appearance of the ECG. Is this original or a replacement? I thought the power train for my truck was pretty original but the more I poke around and learn, the more it looks like decades of pricing stuff together.
