Yes, 3/4 turn after 0 lash

Yup, that’s fine.

Note that you have polylocks vs pinched nuts stock stamped steel rocker arms use.

I’ve been using polylocks since 1988/1989 , so i do it by feel and can’t put that into words. So….i found some instructions for you:

Polylock Adjustment Procedure

Follow the steps below to adjust your Polylocks.

Procedure

1. Set the Valve Lash or Lifter Preload by turning the outer hex nut (polylock body).
2. Loosen the outer hex nut approx. 1/16 of a turn.
3. Tighten the set screw.
4. Tighten BOTH the screw and nut together until they jam and become much harder to turn (25-30 ft.-lbs).

The outer hex nut should be back in the same place it was before you loosened it. Recheck your lash setting. If it's off, loosen up the polylock and try again.

17 inHG is good normal vacuum at idle.
5.8 psi of boost is good boost pressure and I wouldn't try to increase that until you get everything else sorted out.

Your fuel pressure regulator should have its reference hose connected to the carb box.
Your fuel pressure gauge should be connected to the fuel line between the pump and the box.

Your box will NEVER be in a vacuum situation. It will be at positive pressure any time the supercharger is spinning.

Your idle fuel pressure should be around 7 psi.
As the pressure IN THE BOX rises. Your fuel pressure should also rise.

If you are seeing 5.8 psi of manifold pressure (in the intake) then your fuel pressure at that time should be around 13 psi.

If all this is true, then you can start tuning and optimizing.

ok i'll do like you posted me..tnx

great...so far so god...my fuel pressure at idle is 9 psi and when boost comes it is oround 12 psi..very god tips...thank you very much
