For those who have changed the math from the OEM specs of the long block – ie using different thickness head gaskets, using decked heads, using phase two heads with a phase 2 heads on a phase 2 block etc – Using two adjusters will allow you to ensure timing is accurate, and each side of the engine is working harmoniously.
CNC machined from billet 6061 aluminum and are sold as a complete kit, ready to install on your motor.
For changing timing, we recommend using one adjuster for fine tuning 3-4 degrees. Moving the timing belt one tooth on the cam gears will net a 7-8 degree change. Then using the adjuster will allow the user to fine tune above or below that 7-8 degree change.
***ONE ADJUSTER IS NEEDED FOR ADJUSTING CAM TIMING ON OEM-SPEC LONG BLOCKS***
***TWO ADJUSTERS ARE NEEDED FOR SITUATIONS WHERE THE MATH OF THE LONG BLOCK AS BEEN CHANGED – THICKER HEAD GASKETS, DECKED HEADS…ETC***
