I can't imagine trying to do this at those temps! Yes surely that's 
at least a part of your problem.  Also, since you're replacing the 
core, I assume you've already disconnected the heater hoses? They 
certainly could offer lots of resistance when so cold.

One thing I'll mention if you've not already done it: I found I had 
better access (and more room for prying up the box) after I cut all 
the cable ties that hold the wiring harness that runs next to the 
delicate A/C tubing along the top edge of the firewall.  The harness 
doesn't look like much, but every 1/4" of clearance helps.
