I have two 340 six pack intakes. One has part number 3418682 and also says LD6B. The second has part number 3418681 but no LD6B. I think the 681 could be an original but not sure. Any way to tell?
340-6 Intake manifold part numbers. Original?

mine doesn't have the LD6B either , why ?
O.K. the 3418681 is O.E., the one with the LD6B is over the counter Edelbrock that anyone could buy, the 3418682 was a after market one that Edelbrock made but only a few and went back to the 81 part #. Not sure what that was all about but I have only seen about 3 of them.

I have a original one. Brian is 100% correct.
The LD6B one is like brand new. Looks like as-cast inside of it. If they went back to the 81 PN, how do you tell an original from a replacement? Is there any way to say 100% that it came on a TA or AAR?
thats what i was told on mine . i did get the factory air cleaner with it . but this one fits the 64 barracuda its set for . 340 6pck should move my little cuda around , lol .
I have never seen a throttle bracket for a 3 piece kick down for a 340 6 pack, all the t/a's used a 1 piece.

Linkage should look like this.
well its not going to be used in my set up , going to use an a833 behind the 340 .
i did this on my 440 6pck hotrod set up . put the trans shift kick down in the throttle linkage . cleaned it up .

Why did you write casting numbers on my wall on my profile page?
putting this setup together for a driven 383 , there barry grants's small cfm carbs .
Nice, what’s the cfm rating of the carbs?
barry grant's reworked setup is a true 250 cfm a carb , so 750 cfm total .
