Not really sure exactly what you are asking cause of the wording but the K-members are not the same from small block Charger to big block Charger. If you are asking if a 76 Cordoba K will fit your 73 Charger then Yes it will work. You will need to use the cordoba k-member to put a big block in your car. Also the passenger side engine pan is different you will have to trim that out so the headers fit,don't really know about stock manifolds never tried it but I doubt they will work since the factory redesigned them for a reason....

'73 and later used the isolated K-Member. According to the engine-swap book I have, there are three (a Slant-6 K-member, A-engine K-member and B-engine K-member.) Schumacher Creative Services has special motor-mount swap kits that allows the B-engine (big-block) to be mounted to the A-engine (small block) K-member. It's $174 including shipping. Here is a link: Schumacher Engine-swap link

This is the only way to go if the OP does not want to change the K frame , the swap to SPOOL mounts CHANGED the way things are located on the K frames , if you drop a big block on a smallblock spool mount K in an A body the trans mount will not bolt to the trans because the bolt holes are off by almost 1".

73 is what I have heard also. The mounts will be the way to go if you don't want to swap K frames. Don't forget to make plans for wiring, cooling, exhaust and other stuff that are part of a swap. I'd suggest looking at http://www.bigblockdart.com/for some ideas on all the extras that need to be addressed too.

Like said previously, the Big Blocks used a different K-frame from 73 up. You will need to change the K frame or get the schumaker mounts.
2) the b 727 is for colombe fhift, the a 904 is floor shift, what do I need to keep the slap stick?
The shifter rod bracket on the back of the tranny is different on a 727 than a 904. If you follow the rod coming vertically down from the inside of the car the bottom of it fits in a bushing that is held by a bracket. That bracket is different. They look the same but are different if you compare them side by side. I think the rod from the tranny lever to the vertical rod is the same but I am not sure.
3) will the codoba motor mounts work?
Only if used with the correct big block K-frame.
One of these is 727 and one is 904 but I can not remember which one is which.

Big and small blocks with spool mounts have completey different motor mounting positions. I did this swap and still regret it.. The iso bumpers were a solid mass of rust and the k frame bolts broke off inside the frame or broke the cage nuts loose so I had a ton of work to change the K frame. The Big Block K frame spool mount from a Cordoba or factory Charger requires a different oil pan and pick up than anything else...

Hopefully since he is in SC and not Chicago the rust won't be too bad. I changed more than one set of rubber bushings/K-frames but they were southern cars. It's not too bad, assuming the engine is out. 1. Disconnect the brake lines. 2. Unload and Remove Tbars. 3. Remove the 4 bolts under the Upper control Arm that hold the UCA bracket to the K-frame. 4. Remove the pin holding the Steering shaft to the steering box or unbolt the rag joint. 5. Remove the 4 bolts to the K-frame a Muscle it out. Older cars with a front splash pan will need the pan removed in most cases. This will drop the K-frame complete with front suspension. But like you said the rust adds a new factor to the problem.
