Like mentioned above, could be a blend door issue also, and for anyone looking at replacing the core I highly recommend pulling the dash and heater box apart. I know its more involved but doing things right has a bigger reward. The last one I did the A/C evaporator was plugged up resulting in almost no air flow. Thanks Dodge for not giving us a cabin air filter....
I have a 96 so the blend door is cable activated. I just did the heater core the proper way

How did you bleed the system? Any air still trapped and it won't heat up enough.

Once I replaced the heater core, I used one of those spill free funnel kits that attach and seal to the rad. Supposed to get rid of all air once the truck is running for awhile and once the thermostat opens up and all bubbles are gone from the funnel all air is supposed to be gone.
