Default Holley jets

Looking for a chart that lists Holley jets and their corresponding drill size.
I have seen all the charts for up to 100 jets. But I want something that goes beyond 100 jets.

Thanks

That is not the chart I was referring to. I've never seen this one before.

I could use that chart as well.
Anyone?

Or any of the other charts.
Do the air bleeds and emulsion holes go by 'normal' numbers?

Doesn't look as if there was any closure on this. Anyone have definitive information on which chart is correct? Also, what damn drill bits do you use?

It doesn't seem that a standard drill bit set would have all the proper orifice sizes to give a full range of versatility for a DIYer.

Thanks that looks to be very helpful. Now only to measure the drill bits and see how they correlate to the orifice sizes. This has to exist somewhere already but I can't find it.

Thanks

If you ran out of jet sizing because you need more fuel why don't you just go one size smaller on the high speed air bleeds. That will drop you down about 10 jet sizes to get the same amount of fuel.
