I have a 1957 T-bird that has an engine serial number starting with ECZ; and the shop manual shows ECJ for the Bird's 312 ci. I'm wondering what car the ECZ identification came from. Can anyone help?

Am having the engine in my newly purchased 1957 Thunderbird rebuilt; and the color on the engine is orange, the tranny is black. I like to paint both the original color, as if the car just came out of the Ford factory. The engine is 312 cid, the tranny is standard fordomatic (two speed). Can anyone help me?
