Replacing 273 with a 440 in a Barracuda

No, that k-member will not work with the DC measurements, but you can fab up mounts to work with that k-member or buy Schumacher. I prefer the DC k-member, but the 73-76 V8 k-members are getting very hard to find. I used to always have a couple on hand. Right now the only one I have is for my '67 Barracuda convertible.
