What jets come stock in a Holley 650 DP carb?
-Can anyone with a DP carb tell me what jets they come with?
-Also do they come with any extra jets to tune a little?
-What power valve do they have stock?
-Do the Holley DP carbs have a power valve on the secondary side too?
I want to get a holley DP carb tomorrow. I usually have to jet my carbs a lot leaner for 6000 feet elevation and I wanted to get an assortment of jets, but I noticed that the packs only come with jets from 64 up. What if I need some smaller. Do they sell a smaller jet pack?

Page 2. Need 150% to read it on my computer/monitor.
Looks like 67/73/6.5 for a 0-4777 (mine was a -7, but was used and rejetted). No secondary PV. The 6.5 will probably be fine.
No extra jets come with it. Get the 64-99 assortment - well worth the $40, even though you'll probably never use the larger sizes. You may find you'll actually need to jet up from the provided jets. If you need smaller than 64, you'll have to get them $5/pr. Life could be worse, however.
