It's a stock 170, with Load-O-Matic set-up and heated carb spacer in a '61 Ranchero. I'm installing a Classic Auto Air heat/defrost/AC unit.
The original heater had constant flow of coolant through the core, so coolant also was always supplied to the spacer. The after-market unit has a cable-operated valve to control the coolant flow to the
heater. When I close it for summer driving, no coolant will flow to the spacer. When I open it during cold weather, it's back to full flow to the spacer.
I know there are opposing views about the value of the heated spacer, but either way, I doubt that it's a good idea to have it sometimes and not at other times. I'd think it would be impossible to tune for both conditions.
I know I can just plumb around it and forget it, but wondered if anyone had any thoughts.
