Define swap kit. Schumacher makes conversion mounts to let you put your 340 where a /6 was, but there are a bunch of other differences as well.
that would be the very most basic kit you could get.
When I converted my 72 Swinger from /6 to 360 I had to swap the radiator, the throttle cable, the transmission and kickdown, the exhaust, the radiator hoses, the AC hoses, all the accessories, probably could have just swap the mounts but the 360 came from a donor so it was dressed. some of the wires needed length adjustments.
I am probably missing a few other things, but this was back in 93 so it's been awhile and no one was making a kit nor was there a Moparts back then. I did my research, had everything on hand and the swap took me on day to do. I was fully prepped and probably had several days worth of prep done before the swap started.

On a side note '92/early 93 magnum ex manifolds have a ~2 & 5/16" outlet as opposed to a 1&5/8" outlet on the later ones. A guy on FABO is selling ported out manis & you might peruse his post to see what info can be gleaned from it. (might be under "mechanical parts for sale"). I was thinking that a 68-70 340 pass ex mani flows the best (for the pass side) but are rare & very pricey but if I read his thread correctly he is sayin the large mag one does or maybe he is referring to his ported ones (I need to get back over there myself).

Careful with the information, I am 98% sure T that there is NOT a conversion mount for installing a V8 on the slant 6 k member in the 66 67 Coronet. Even all the way to 70 b body even.
You will need to use motor plates or swap the K member, to a v8 K.
they are pretty ubiquitous. I have had one for sale ($100)for about 6 swap meets

Looks like you are correct

Well, you'll just have to cut and paste the mounts on the K member.

I think if I was gonna make my own I'd bolt a set of late model spool mounts to the block, use the trans mount to locate the assembly fore and aft and make a U shaped adapter to bolt the spool mounts to the K member, or cut off the existing mount stands and weld the U shaped adapters tot eh K member.

I know the spool mounts are available new at Napa...probably most any other parts store also...Picked up a set last summer when we put the motor in the Duster... I think you could tell them you need them for an 86 Diplomat...IIRC they're the same clear back to the 73-up A bodies...
...FAFO...

Be advised that all of the current production aftermarket spool mounts are the wider driver's side 318 units. You will need a spacer on that mount to make up the difference. You can see this in the pic of the 360 I was prepping to put into my 87 Diplomat, I used some washers I had lying about.

Trans Dapt might have mounts. It may not be that big of a deal. The passenger side k-frame mount is probably in the same place, and the driver's side isn't far off. Test fit a bare block and trans case, it may not be too bad.
