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

[rr4406pak]

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.

Yes. Likely the condenser is smaller than a 440 would have as it would have a wider radiator. Under the dash would be the same.

Biggest issue is the brackets to work on the 440 and compressor. Most people go with a Sanden compressor and custom brackets...

If budget is a issue,it can be done with BB compressor brackets. I agree with both above as far as condenser mounting and radiator size. If it is in your budget, A Sanden compressor conversion is the way to go.

And don't forget that you have to mod the blower motor/box to fit the 440, with or without AC.
A couple good options in the How To section- just remember your AC box may vary a bit, these articles focus on the standard heater box.
