I could have sworn I posted this earlier but can't find it, so I must have hit the wrong button.

I plan on installing a new engine/tranny into my 1956 Thunderbird in the near future. I happened to notice the heater core on the firewall and was wondering how does one test a heater core to tell if it should be repaired or replaced? Can it be tested while still on the car? Does it need to be pressure tested at a radiator shop? I don't know the history of this core, but it looks to be in good shape from the outside. It did have both heater hoses attached to it before I removed the old engine. I don't know if the heater worked before I removed the old engine. Any advice would be appreciated.
