"ONE REQUEST: If you notice anything about the setup that is not correct for a 1973 H-code Mach 1, please let me know. The car should be entirely correct in factory condition."
The air cleaner snorkel is not correct.. It should be the one that connects to an accordion style cold air tube. The accordion connected to a 2-piece plastic cold air plenum that ran under the battery tray and connected to the radiator support.. All 73 cars had the cold air intake as part of the emissions requirements, which also included the EGR plate under the carburetor. I you would like I can get a picture of it on my 73 coupe and post it tomorrow.. In 1972 only the California cars and all of the 351 H.O. cars had the cold air tube..
