Hey guys. This just came in the other day. It's a 327 Chev with a Holley something on top. I think its missing some kind of throttle linkage as well as something for the kickdown rod off the T350. Anyone want to have a stab at what kind of carbi? or what linkage I need. That spring is all wrong also, by the looks? thanks gents. All help appreciated. At the moment the throttle cable doesn't spring back and as you may be able to see, someone has put a dodgy bracket on the kickdown rod.
The carb has a number's on the front, write them down and post. It looks to be a 600 cfm. Where's curious George?
Looks like missing the linkage to the secondary throttle shaft and you will have to fab up something to pull on the kick down cable.
This is what unit it should have instead if you stay with the same cfm. Click on the 360 view. http://www.summitracing.com/parts/hly-0-80450/overview/
The linkage that is missing is to manually close the secondaries. When you get off full throttle you want the secondaries to close. Helps you slow down and stuff. That linkage does that for you. It needs to be there. All Holley vacuum secondary carbs have that link originally, so they are easy to find. Some US Fords of the 70s and 80s had Holley carbs as OE. Maybe you can find a Holley-equipped car or truck and grab the link (leave the carb). Your carb has an abbreviated throttle linkage plate. For the kickdown I suggest a cable unit like the Lokar. You will have to fab a bracket onto the throttle plate but it won't be too painful. Lift up that plastic collar and write down the LIST number on the choke horn and post that. Let's see what this critter's name is.
I certainly ain't a guru but it's definitely a 600CFM 4160 with externally adjustable floats n' a vented float chamber. Like the dude above me said: post up the list number stamped on the front of driver's side choke horn. I'm gonna' bet it starts with R1849 or R1850...
The OP's Carb is a 80453, for Fords. Yes the secondary link is missing, easy fix. But the throttle shaft has no provision to connect any sort of kick down. Even a Lokar. If that carb is to be used, a replacement shaft is in order but one for a GM 4160 series. Or, have a universal 1850 as sample to copy and fab the missing lower half of the lever and weld in place.
Beautiful, thanks guys! Dead on the money. LIST 1849 0595 (I think)on the second line beneath it. Great info guys.
Johnny. Another guy from a different forum said the same thing. The kickdown bracket for a Chev hangs down lower than the Ford unit. This is getting wierder and wierderer
Agreed. Now, what does the OP do? The problem at hand is a missing link and no kick down hook up. Because L79 was a pedal car or stick shift (no kick down neeeded). The best thing to do is leave that carb alone. Don't even do what I mentioned earlier about fabing and welding. The carb is worth to much to be Fd with. Just get the GM unit I listed above (reply #6) using Summit as a link to see. Check this out http://www.ebay.com/itm/Original-GM...r_Truck_Parts_Accessories&hash=item5659fb883e
List 1849 is necessarily an L79 carb. As Johnny Gee said, it has a Ford linkage plate, and the List 1849 was first used on Mercury cars in 1959 with a 383. They were also available over the counter as an aftermarket carb, and the 4 digit date code (0595) may be indicative of an aftermarket carb. Factory issued carbs would usually have a 3 digit date code, and the choke horn would be stamped with an alphanumeric code for a Ford starting with B9, or a GM carb would have a 7 digit part number that would probably start with a 3. They are 550 cfm, and worked well in dual quad applications too. That said, I have nothing to offer about how to hook up a kick down linkage. Maybe swap the throttle shaft with one from a 1850 or other 600cfm carb, as the ****erfly plates should be the same size.
Gents, as usual, your feedback is greatly appreciated. I knew I was in the right place to ask the right questions I think, knowing all this, I might track down a more suitable carb.
So, if it's a bit of a rare beast I guess I shouldn't pilfer bits off it if I get another carb? Is it worth a coupla bucks?
Never mind the carb what is that "funky" looking cable with a holed piece of universal bracket soldered to it hooked up to?
Yes, I would call that a (not very) highly sophisticated multipurpose bracket designed to do many things...to look good is not one of them. I guess it might have worked once upon a time. ****** scary.
more than likely someone swapped the base plate out as the missing linkage kind of points to it , people did that when they would find one that had sticky or frozen throttle plates , I have gotten a few this way over the years , drives you nuts trying to figure out what it actually is other than the list number . but number wise if its a ford lower combined with a gm upper its still worth money . I would get a #1850 ( 600 cfm vac sec carb to solve your )problems .
exactly what I did. Thanks for some outstanding info there, guys. Made my decision much easier. Was lucky enough to pick up a new unused 1850 unit just out of town. Bolted her up...she fired up first go, straight outta the box.
