I have a 1957 Ford retractable with a 312 cu.in. motor/w 4 barrel carb. What is the correct sized air cleaner for it? I have three of them to pick from. They measure 14'1/2", 16 1/2" and 18" diameters My guess is that the smallest is for the 292 Y block, the 16 1/2" is for the 312 y block and the 18" diameter is for something later like maybe a 332, 352 or even maybe a 390 cu inch? In the attached photos, you will notice that even the air intakes on the air filter bodies are of three different sizes too. Please help me pick the correct air cleaner. I would like my retractable to be as Ford sold it.
