Looking for a kickdown rod for a 68 RR with a 383/727. Part #10 in the pic.
Also, be aware the throttle bracket is different between 2 barrel and 4 barrel. They both position the kickdown in the same spot, so the rod going to the carb needs to be longer with a 4 barrel. But the throttle cable mount is over 1/2” fwd. In my pic, the 4 barrel bracket is on the left and 2 barrel on the right.

. U need to measure with out the adjuster on it. That is a small block rod being how short it is. 273/318. There is also different length adjusters. KimThis is the one I have that does not work. The bends are incorrect and it hits on the exhaust manifold not to mention the one shown in the FSM has a clevis on the end. The length on the one in the pic looks to be the correct length though.

So ur saying a 340 rod is longer than a 440 rod? Idt so. KimThat looks like a small block piece you have. A big block will have the top half straight. And the bottom is attached by the clip in my pic, not a clevis. The top in my pic is big block 440, and bottom is small block.
Also, some say that 383 is a different length than the 440, but nobody has ever shown proof. I think all big blocks were the same length and the height difference is made up by the long length of threads at the top.

Ok, I just realized I took some pics and measurements of the 2 bbl linkage from a 400 in a truck. The top rod will be too short for a four barrel. Kim
