After my recent issues with the correct original Holley on my 66 327/300, I started looking into a new carb. From what I have found, Holley still makes the 3367, but it is only sold through one vendor. After calling the number that Holley gave me it turns out to be "thepartslady" off of ebay. I would like to know if anyone has experience with this company, good, bad or otherwise - please comment. Also, is this company truly the only vendor still selling new 3367s? Or does anyone know of another vendor out there?
I don't think you are going to get a better deal on a new 3367 then from the partsladi. They seem to sell a lot of new parts if you read their feedback comments. There is a NOS? 3367 on ebay now from someone else, at a Buy it Now of just under 2 grand.
I did buy a 67 new repro turn signal switch from the partsladi, and had no problem.
However, maybe not give up on your original yet. I went back through your previous thread, and the problems you cited of whistling and inability to lean out, could also be related to your secondary throttle plate being too far open.
That's a simple adjustment, but most of the comments to that thread are related to the throttle plate and potential warpage. The plate could be warped, or the throttle shafts could be worn and leaking, and you have less vacuum running throught the air horn.
Before you thrash your original, why not try a new replacement throttle plate assembly. They are about $125-$150 and it might solve all of your problems. I know it did for my 3810. If you do it, get the bottom of the carb body planed.
Mztercar or the carbguy on ebay have the throttle plate assemblies, maybe the partsladi also has them. I think I got mine from the carbguy.
Happy New Year,

Great suggestions - thank you. I don't want to give up on the original, but most people tell me that nothing helps an engine run better than a new carb. I would keep the original and most likely have it rebuilt by Bob Kunz (spelling?). The car already earned a Top Flight, so the missing date on the new carb won't make or break the car.
Again, thank you for your suggestions and I will look into it. However, I must admit that for me bolting a new carb on is one thing, rebuilding the existing is another. I just don't have the experience and don't want to screw up the original.
Regards,
Rob
BTW - I have an uncle who lives up the road from Murpheys not far from you. You live in a nice place and I always like visiting that part of the state. Enjoy the new year!
Here's another suggestion. Buy one of those 4160 generic Holley's (at Kragens)to keep your car on the road. Then you have the time to play around with your original, you can send it out, or experiment yourself. You'll probably have to change the pump to carb fuel line.
Probably the throttle plate assembly is the most worn part of your carb. If you saw what they put in the originals for throttle shaft bushings, you would laugh. I did, they are teflon impregnated plastic tape. Over years of use the primary shaft bearings are probably egg shaped.
I think a new throttle plate assembly will probably do wonders for your car. But check the plane of the base of the body and metering body/plate surfaces. If warped have the body surfaces planed. Then physically bend the metering plate and block flat if warped.
Put it back together with a new gaskets and you will probably be good to go.
BTW Murphys, CA is getting to be quite a nice little tourist town, with all the little wineries, and events at Kautz Winery. Next time you go up to see your uncle, let me know. I'm 30 minutes away in Sonora (20 with my 67 on the back roads).

If your carb is an original, dated #3367, could you do me a favor and tell me if your primary throttle plates open fully (90 degrees to the bores) with the throttle lever full open against the mechanical stop?
I have a 65 dated 3139-1 (just about equivalent to the 3367) and a replacement dated 3810 both on the shelf. Just checked them both and the primary throttle plate is at a full 90 degrees to the body at WOT (with the inboard throttle lever against the fixed stop). Got to admit that the 3810 replacement inboard throttle lever has a little looseness in it, about 5 to 10 degrees. The 65 chevelle 396 3139-1 has much less throttle play, maybe 1 to 2 degrees.

Thanks Jerry....I don't really want to fool around and try to reposition the inner lever if was intended to be where it is. It's not loose, nor does it appear to have been repositioned I have a replacement #3367 and #3605 and the primary throttle plates on both of them open fully as well. I'll check with Holley directly and see if they have anything interesting to say.
