I have a friend of a friend selling a pair of Weber DGVs, atleast I think that's what he's got. He said he has a pair of Weber carbs for an early Z car. My question is, what should I look for when examining these for quality and completness? Is there special throttle linkage hardware I'm going to need or do they use the throttle linkage from the stock manifold? What other special pieces are needed for the install, if any? Are there any spots or components I should look at with regards to wear, deterioration etc.

Lastly, and probably a very subjective topic well covered here, does it make sense to even consider these over the earlier round-top SUs I already have on my 73? If not, could I get more than $50 reselling them on eBay?

Keep the round top SU's they are better.

In my opinion they are better than the su setup I had good su's on my car, but if you tune the dgv right got to get the mixture down they are great. You will need to remove the carb spacers and get all the linkage you can up tp at least firewall you can make some of your own stuff if you want, would almost be better to have a cable setup. Just make sure the carbs are clean and in good working order, and make sure you hook up the water heat pipe the the canon intake or you will have puddling of fuel and that is no good at all. I would say if you have any smog stuff on the car and it does not need to be smogged get some plugs plug the holes from the smog stuff on the balance tube, this setup as well works good with open exhaust. but just take care and get it setup right, if you decide you can make some good money off of them. Fairly basic procedure so just have fun put it together and take your time make sure to clean everything and go get some gasket paper to make your own gaskets. Oh don't forget the throttle return spring, , and to mess with all the linkage and don't bind the linkage screws. you can get more info and redline webber website, also car will start better but is progressive so will be slightly trickier to start but not a prob, it will act more like a ferrari all through through the rev range, smooth and quick, little easier to keep in check than tripples, but those are still better. So good luck with that, and don't listen to all the negative from these people, the four bbl is a good swap out as well, but thats my opinion just one guy who plays with carbs.

In my experience the su's performance overall was preferable to the DGV's The Webers were great for mileage, but a good set of tuned and maintained su's is tough to beat for performance unless you go to triples.

I have been having the damndest time just identifying the carbs on my car (there is a pretty good shot of them in my gallery). I am in the process of trying to decide whether to rip them out or rebuild/retune them (I have no experience with this, but am willing to buy all the books and learn). I have a pretty good sense at this point what an SU setup will cost me, but I have no idea what a rebuild kit for the webers will set me back as I really don't know what model they are. Is there a good way to determine this before I go out and buy the books? Thanks!

Not DCOE (side draft), so I assume they must be the down draft 2 bbl (twin choke) DGVs.

Go here and do a comparison. Perhaps you can find a part nunmber and compare it to yours.

very helpful, thanks =) I'll have to take a closer look today and see what I can figure out.

Edit: Looks like 32/36 DGV 5A

Anyone feel free to confirm/deny =)

Thanks Enigma and Arne! Sorry to hijack the thread, I'll post more questions in a new thread.
