I recently noticed the oil filler/breather tube on a 312 '57 Mercury is somewhat shorter than the one on my '64 truck. Since the trucks had the exhaust crossover,  I'm guessing the filler tube was made longer to provide a safer access. The truck tube is 8". What is the length of the shorter versions? I believe the 60-62 Y-block Ford products anso had a short filler tube with a slight offset to clear the cooling system expansion tank?  I'm going to trim some off just because I think it looks a bit neater/cleaner. Thanks in advance...............
