The difference would be where the cable and kick down attach due to the intake being wider because of the raised deck. The rod down to the trans is also taller for the 440 due to the raised deck. Those do look like 440 pieces you have but the rod is hard to tell as it disappears behind the engine. I would start with getting the thick gasket used on AVS carbs, that will raise the carb close to 1/2". Does the throttle cable and linkage lever appear to connect to the carb straight looking down on them?

Possibly because the "C" shaped link is standing near verticle, in some installations it leans forward at an angle which would bring the top link closer to horizontal. That would also close up the gap in the slot. Looking at it again after John mentioned this I can see your problem and I believe it is caused because you have run out of adjustment on the rod going down to the trans which is not allowing the carb attachment to go fully forward. Did you piece this setup together, you may have the wrong lever down at the trans wich is why it is at the end of travel , or you put it on upside down ?

Nope - If you're looking straight on the engine from in front of the car, it's cocked at a wierd angle over to the right to connect to the stud on the carb bracket. My guess now is that I have a 440 bracket on the intake and possibly a 440 linkage rod because the accelerator cable is too far to the right of the carb/stud linkage. I'll take some more pics when I get home from work.

Did you piece this setup together, you may have the wrong lever down at the trans wich is why it is at the end of travel , or you put it on upside down ? Did you miss this ? unbolt the down rod and see if everything levels out and it pulls forward, if it does you either have the wrong throttle cable bracket or the lower rod is too short/bent wrong or the lever on the trans is the wrong oreintation. I asked , is this parts from one source or did you piece it together ?

I think you might have the wrong kickdown rod to the trans or the trans kickdown lever is the wrong lenght. I beleive there are 3 different lever lengths. Also, the flat bar on going to the carb is different than the one on my car. I can double check these items when I get home. Ron

That bracket is a 440 one and you should replace it with the right one. Here is one available at a reasonable cost. http://cgi.ebay.com/ebaymotors/MOPAR-383...=item5ae001dbbe The seller is Jimmy Borros and he knows his 71 up b-body's well, and has helped me out allot over the last couple years.

All adjustments are fine and the angle is level on the slide bar. The source of the problem is with the edelbrock carb itself, it pushes the throttle stud over to the driver side of the car �� more than with the Holley and creates the awkward sidewards angle of the slide bar. The height of the throttle stud when mounted on the Edelbrock is also a little lower, hence the weird downward angle on the slide bar. This makes sense since the original carb on a 71 RR was a Holley and is what the original linkage was designed for. Time to rethink the carb choice and if anyone can use an absolutely brand new Edelbrock 750 electric choke model 1411 carb, never even run, let me know. I am certain this will fit 68-70 B-body big blocks with no kickdown linkage issues as the throttle stud is in the exact factory location where it needs to be. This makes sense since the Edelbrock is an AVS design and that's the original carb on my Bee. I wonder if anyone out there is running an Edelbrock carb on a 71-72 B-body big block with factory kickdown linkage without any issues - if so, I'd like to hear from you. Thanks again to everyone who took the time to reply.

Couldnt think of a better reason to get rid of a 1411/1407 Junk Edelbrock Anyways And yes , with the correct kickdown linkage the Edelbrocks work fine - I ran the 1407 and newer Edelbrock 800 without any issues at all when it came to the factory correct kickdown linkage and edelbrock adapter I was also under the impression the 71 383 Magnums with Auto Trans left the factory with the Carter 6125S Avs - The Holleys came on the 4-Speed Cars ???

What Holley do you have , the original or an aftermarket with the Chrysler adapter ? Why would you remove a holley and put on that junk performer 750 , Everything I read on the internet says Holleys are the best carburetors ever built ?

A lot of free play 1971 383 Magnum one piece rod kickdown linkage / bracket 1971 Dodge Charger Superbee 2011 Ram Sport 1500 Quad Cab Deep Water Blue Loaded Siberian Huskies
