Holley Ultra XP

[pwtjr]

Anyone running Holley's new Ultra XP carb?
I am carb shopping and looking for reviews/comments, particularly on their 850.

i have one, i never ran it out of the box, i took it to fuel curve west out here in Cali and had it "prepped" before running it on my stock stroke 440.

it has some minor manufacturing flaws that were corrected with the boosters, and i had the Pink cams installed along with Quick Fuel power valves and gaskets, (better disigns) awesome carb, with alot of tunability.
