I've got a '68 dated 3418 carb that I was running on my LS7 for a while. I've since come across an 850 double pumper that is on there now, not to mention the dirt cheap Dominator I'm about to get from a friend of mine. I put a kit in it a few weeks ago, so everything is fresh. Not for sure I'm going to sell it, but the thought has crossed my mind. Here is the info off the carb:
List Number- 3418-1
GM#- 3886091-AN
Date Code- 841 (The info I found says first week of April, 1968.)
Primary Metering Block- 5247
Secondary Metering Block- 5253
It has the factory staggered jets, 6.5 power valves at both ends, and light yellow secondary spring. The only thing I do not have for it is the choke assembly. Any idea what would be a fair asking price should I decide to sell it. I've been told the fact that it's a '68 dated carb ,versus '67, hurts the value a little bit. Any info would be appreciated.

Which 850 do you have? I have a 4780 800cfm Holley (mechanical secondaries) mounted on a 3933163 intake and it has to be shimmed up for clearance against the manifold. If I cant find a way to make it work without so much shim I may be forced to switch to a factory type Holley like a 3418. Have you ran into any clearance issues? As for value, a good way is to check the closed auctions on Ebay and see what they are bringing.

It is the vacuum secondary model. When I first ran the carb it was on a 163 intake and had no clearance issues.
I looked on Ebay, but the numbers seemed all over the place, so I figured I'd ask on here.
