Holley 390 6299-1 vs 0-8007K

Hey Guys,

Anyone have experience with the Holley 390 6299-1? There's one about locally on Craigslist and its a lot damn cheaper than getting the 0-8007 brand new...

From what I've been able to find it seems that it was an emissions era carb, I feel that may be exactly what I want as my engine is still pretty much stock and I've heard that the 0-8007 can be a little much for a stock engine

Anyway, just wondering if anyone has one of these on their slant and if that have any advice to offer

Thanks!
