I converted from reverse flow to old school reg coolant flow and I have NO warm air blowing through vents and the truck is NOT running hot 180-190 temp.

Things I checked:
1. Wiring. Made sure all flapper doors are working.
2. Leaks. Found none.
3. Correct coolant level.
4. Flushed lines and all old coolant before installing new motor.

I can hear the flapper door moving when I change the setting on the dash but still no warm air.

As you look @ the heater hose fitting from the front of the truck, the left hose is going to the rad fitting(same as stock) and the right hose is going to fitting on water pump(used to be on rear of intake manifold).
Am I doing something wrong? I have been working on this for 2 days. Any ideas???
