Having problem getting the vacuum to the heater / AC controls to work correctly. Losing vacuum. Has anyone found / designed a replacement (Say electronic) to replace the vacuum control? What other alternatives are there, if any?

Thanks for the inputs. I took it for a test drive today and noticed that ithe engine is running rough, not on all cylinders. The carb was adjusted per instructions and is good at idle. Doesn't seem to have any power. I'm going to check compression on the cylinders. Didn't do that before installing the engine, not the smartess think.

I'm finishing up a frame off restoration of a 1967 Lemans Convertible which has a year correct 326 w/ 4 barrel carb (New Edelbrock 1406), new distributor w/Pertronics Elec Ignition module, and backed up with a TH400 transmission. Engine has been tuned, all vacuum leaks sealed, timing set a 12 degrees, and idle at 850 RPMs. Engine is fine until I put the car in gear (Park or Drive). The RPMs drop about 400-500 RPMs, then fluctuates between these numbers, and sometimes dies completely. Any help/suggestions would approciated.
