My sister has an HP on her camaro, it probably 8 years old. It is def richer out of the box than a standard Holley.

The air bleeds make it a lot more tunable. If you are going to run two of them, you'll have to really look at the idle circuit. May be able to rune wiht a bleed, if they give you thant ability. When my dad and I tune the old 1850 600 cfm carbs for dual quads we would tyically put a small restrictor wire in the liquid line of the idle circuit in the metering block.
