A/C delete

Deleting the A/C on my 73 Cuda. Will delete compressor and heater control valve and run hoses direct to heater core. Without changing heater boxes what changes must be made to have heat and more importantly the defrost work?

Nothing. The heater box and defroster don't know the AC is gone. I removed my AC from my 70 Challenger years ago before I moved to Arizona! Thanking about putting it back now!

The holes in the cowl firewall are the biggest cosmetic items that still haunt my car. I removed a dealer-installed A/C unit back in the 1980s. I concur with Xcudame, the heating and cooling circuits are, more or less, separate, and removing the A/C parts has little impact on the heating parts.

I recently discovered that my car is set up that way. does this setup perhaps cause the interior to get warmer when the car is running? any other drawbacks to setting it up in that way?

get warmer? does your car get warmer when running, even though the heat is off?

the heater flow valve control to the left of the steering column will close the valve and stop the flow of heated coolant to the heat exchanger.

but this doesn't stop other sources of heat. A common problem for those using headers, is the heat radiating off the collectors upward to the floor, where it in turn radiates into the interior.
