What are a correct set of dual quad carbs worth? I'm asking about a set that will need complete rebuild, but are the correct numbers for a '66 application. Anyone care to take a guess and help me out?
I really could not guess but do they have all the original linkage parts and such.If they are just the carbs and parts are missing that would stop you from just kitting them and putting them on the value would drop considerably I would think.Maybe provide more info on completeness and condition of them and someone could give you a good idea.
Bruce- Let me add a bit more detail.... I recently bought a manifold and dual carb set-up on Ebay. The auction stated the carbs were original. A progressive linkage was not part of the auction. I got the set-up and it turns out one of the carbs is for a mid-sixties 327 chevy and the other is for a late sixties Buick 340. The carbs are pretty crusty and I knew that up front. Both will need to be rebuilt. I contacted the seller who was ebaying the set-up for a friend. We're trying to work something out as far as adjusting what I paid for versus what I actually got. The seller has been great to work with so far, I believe it was an honest mistake made by someone who doesn't know Buicks, and I'm looking to be fair. So, my carbs above in my first post are hypothetical, unless someone has a set they want to part with. Alternatively, can two carbs that are correct for a single carb application be made to work in a dual carb set-up? If so, what would it take? Make sense?
Ken, How correct do you want to be? Made to work is easy, correct is another. The front carb has no idle adjustment or choke, #3645. The rear carb linkage can be modified to accept the 2x4 linkage. The intakes are different too from 64 to 65/66. The stamping ending in 306 is a 64, 316 is 65/66. If using a stock kickdown bracket you may have trouble using the other wrong intake for your year. The correct rear carb for 65/66 is #3925. I seen all sorts of combinations of carbs on these 2x4 set ups including 327 Vette carbs. There is another guy on the board, Nailheadinags or something like that, that is also looking for a set of carbs. The carbs you have, unless something special for their application, are probably only good for cores. A set of correct, rebuilt and restored carbs may bring up to $1000, cores $500ish maybe, depending on what they need. Kickdown brackets are rare but not impossible to find. Larry
Larry- The intake is a 316 intake. Also, the car is an auto shift '66 Wildcat. I'm not necessarily looking for correct numbers as much as correct performance. If I can manage to get a set of carbs to function properly, I'll be happy. I think someone somewhere in the past got the 327 vette carb and the 340 Buick carb to work as they look like they've been with the intake for a while, but exactly how they performed, who knows. I'm assuming the fact that they are mismatched might be a problem. I want to make sure I can hook up a 2 x 4 linkage, kick down switch, get a good idle, and get at least the same performance I have now with the single carb. Obviously, better performance would be preferred! :3gears: Any input is appreciated.
Ken, From all I have seen the 66 Q-Jet gives equal to or better performance than the 2x4 set up if performance is what you are looking for. There is no equal to the visual of the dual chrome snorkled 2x4 set up when lifting up the hood. "Whadda mean that is stock?" I have thought about trying one on my car. If the carbs you have were modified for the 2x4 linkage and they are rated at about the same CFM's you are 90% of the way there. Do you have the 2x4 kickdown bracket for 65/66? Carmen Faso can probably rebuild the set of carbs you have and make any mod's needed. Larry
I've got a single Carter on there now, so the 2 x 4 should help a bit performance wise. I have to admit my primary reason is for eye candy. It just looks so awesome! I just don't want to step backward in performance. I don't have a kickdown bracket, but I can fab one if I had an example to work off. I've read that Carmen is "the man", so perhaps he can guide me. I also have Tom Telesco just a 20 minute ride away. Any preference for aftermarket linkage? EELCO? Others?
I was just going to say that Carmen Faso is the guy to ask :TU: I remember in February of 2002 typing the same recomendation...my very first post, nervously typing :grin: Carmen has a set of my carbs now, one of which is an original rear for a 4-speed Wildcat :bglasses: Ted
Ken, Carmen did the carbs on my car. I have a set of 64's that are frozen that I'll send him one of these days. I've never used an aftermarket linkage but I'm sure Carmen can set you up. It's nice having Tom T so close. Ask him how the 4:45 posi is doing for me. Larry
Ken: Carmen is the guy. He did my twins too. Good luck finding the correct carbs and brackets. I'm glad to see someone else couldn't leave well enough alone and decided on the eye candy. Rick
Larry, the posi is doing fine after I replaced the burned up clutch plates. Must have been run low on fluid at one point in it's lifetime. It's been all cleaned & detailed. Not put in anything yet, but it's ready when the time comes. Ken, those carbs. can be used, it's just the kickdown with switch pitch that will be hard to fab a bracket for to work correctly. Once I see the carbs. we can go from there. I also have some older AFB's that would probably work. Anything can be made to work, the question is how well????? A properly set-up 2x4 will run circles around any Q-jet. Now a 1000 CFM ThermoQuad is another story, but I still don't like the giant secondary's right above the rear intake ports. All the 4 front ports run lean while the rears run rich. The Q-Jet was no better than my Holley & single 4 manifold off my Riv. when we dyno'ed Bob's engine. The best of course is the 2x4 that Bob runs now.
Ken, you didn't do too bad on your purchase. The manifolds alone have been going for around $300.....there are 2 on there right now, so watch them. I'd guess you could get at least $30 apiece for the carbs you did get. So you're in the hole about $45. I'd suggest offering to return just the carbs, and get a refund for them....As for a fair refund amount....maybe the difference between your price and the final avg selling price of the DQ manifolds now on ebay. The seller did list the carb #'s in your auction...they were wrong for 2x4 carbs...so, he's not entirely at fault. Ya gots ta do yer homework before layin out yer cash! :Smarty: You can just use a matching carb to the one you have now (formerly mine)....you'll just have to fab up some linkage. Just pick out some nice rod ends from a McMaster catalog, and make your own. Or a #3921s is a common 401 Buick carb. Often on e-bay. A pair of those should work nicely. I recently bought a pair of correct carbs with valve covers for $320....would you believe the guy I outbid didn't even make reserve price.....good thing too, since that was Ken! p
Ya had to bring that other auction up, didn't ya Walt! p ou: :laugh: The numbers he posted were date codes and not carb numbers anyway. I knew one was wrong, but the other was in the ball park of being a right date code, so I was hoping for at least one correct carb. He obviously didn't check the numbers themselves as they weren't visible until I hit them with a tooth brush. I was thinking also of seeing where some DQ manifolds ended up on Ebay and go from there. Good idea. Tom, I'm relying on you to help me get something going here. I do have Walt's carb, as he pointed out, and maybe one of the ones I have now can be made to work. I also have a full toolroom at my disposal should some custom bracketry be needed. If you have any dual quad parts (like the bracket you mentioned) perhaps I can borrow it to duplicate it.
Tom's correct........my Quadrajet used to run great, but when I retired it in favor of the dual Carter's the added top end was much more than I had ever expected. :TU: Getting them set up correctly to run good takes some time and patience, though. As for the correct carbs, do talk to Carmen. What you pay vs. the problems you may have making a Chevy carb fit/work would be well worth the $$$. Carmen lives very close to me, I've seen his shop and what he can do. He'll supply you with all the parts you will need that will really fit, and the carbs will be jetted correctly and look like new. As for what a pair might be worth? It all depends on how much the person is willing to pay.......I've seen some sell on ebay for as much as $300 or more. The front carb is the one that's hard to find. :3gears:
Well, spoke to Tom today and will bring the 'Cat to him tomorrow. I need some service done on her anyway and I can then show him the carbs I have. BTW, doesn't this seem unusually high for a DQ manifold?
That's what I was thinking. This new anonymous bidder number thing sucks. People can definitely drive up auctions that way. Plus, you can't tell if you're bidding against a brethren from one of the clubs. I know on several occasions I didn't bid as I recognized I would be bidding against a friend.
