In ‘67 the #616 option became more efficient.

For the #614 portion some changes were made from the previous years.

1) A larger air cleaner base with a different style snorkel and a redesigned chrome lid.

2) The flat sealed AC twist oil cap that was first used in ‘65 on the RH VC is now being used again on the ‘67 on the opposite (LH) valve cover.

3) Likewise the metal pipe from air cleaner to the valve cover is opposite from ‘65.

The #612 portion was also redesigned with different check valves and piping to cylinder head brackets.
