A/C --> Slant 6 --> 440?

I have a 1969 Dart with a Slant 6 with it's original A/C and the A/C works great.
I'm taking the Slant 6 out and dropping in a 440.
Question is, can I use the same A/C system with the big block 440 in there?

Would all I have to do is get different compressor mounting brackets? Or would I need a different compressor altogether? Could I keep/use everything else in the system?
Thanks.
