Default Holley Carb Spec Question

Where can I get primary/secondary jet, air bleed and metering block emulsion air bleed size, PV set up and squirted size information for an out of the box Holley 950 HP carb with mechanical secondaries?

Usually google the PN or model # and go from there

If you know the LST number you can probably find it here in the attached PDF (under Carb Number) along with most of the data you're requesting...

Good luck... GUSTO

You have to call the Holley tech line - they don't publish all those numbers. The published info is limited to jet sizes, PV spec, squirter sizes and some of the other more common specs.

You can get a set of pin drills ( not expesive ) and measure them with the ends of the drills. The jets should be stamped with the number

I had to get one of these the read the stamping.
