1X Cam Signal
Here is my version of a 1x cam signal for the Holley sequential port EFI. I started with a stub out from BOP, and made up the machined pieces to build up the extra length necessary to allow for a Hall effect sensor mounted vertically.
Inside there is a shutter type of wheel with a notch to give a “falling edge” trigger to the sensor. The pieces will be hard anodized after fit check. Note the cam drive gear is upside down in the photos. Motor is a 461 with Old Faithful HR cam (modified to 114 LSA), and KRE 305 CFM heads.  Hall effect sensor  Shutter wheel with cap removed  Cap inverted with sensor protruding through  Steel washers fabbed up to keep the distrubtor clamp from tearing up the soft aluminum   Mock up on the block

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
