Uhh......if it's hydraulic it is 1/2 turn past 0. (IRON HEADS) 3/4 TO 1 turn past 0 on alum. heads.

Hyd cams generally don't run "lash".

0 lash plus 1/2 - 1 turn. Make sure that you set with the cam on the base circle and the plunger at the top of the travel not bottomed out.


Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

0 lash then 1/2 turn. when exh.valve is open, adjust intake(lifter will be on base circle of lobe) when intake goes past full lift and starts to close,adjust the exh( lifter will be on base circle of lobe. good luck.

Thanks! I'm such a dunce! Haven't had a hydralic cam in over 10 years and forgot that they need preload and no lash. Working with my big motors makes me forget about the smaller stuff.
