Here is a picture of the original intake/carb that I ran for a while on my 66 YH 421 that I put in my 66 Tempest. The engine came out of a wrecked 66 Catalina. The air cleaner is from a GTO but the intake and AFB carb are correct and original to the engine. The carb number is 4037S. I can take a closer picture of the choke setup if you would like. The choke system has a tube that comes from the heat crossover and goes to the choke stove to heat the choke coil up.
