Need opinions on factory heaters

I have a 93 crewcab F350 that I swapped a DT360 into over the summer. I had to cut the firewall and build a doghouse, so all the original heater and ducts had to go. Now I am looking to cobble something together, and because I am a cheap-arse, I am trying to work with stuff I already have. I am thinking I can use a heater from one of my parts Broncos. Going to cut the "leg" off that goes from the blower to the outlets, then turn it 90 degrees and bolt it to passenger side firewall, then feed it into my defrost ports in dash. Before I go through all this trouble, I am wondering if the heater is up to warming a full size crew cab?? It seems to me the area being heated is roughly the same between a fulltop EB and a fullsize crewcab, with the crewcab maybe having less room, plus the crew should be better insulated I would think. All of my EB's have been topless trail rigs or racing machines, with the exception of my first one back in the late 80's, and I only had a top and heater in it for one winter. As I recall, it never got terribly warm in it, but it had rust holes and other drafts. Climate in question is in the midwest.

I'm just now doing the upgrade on my EB heater with the larger fan/blower and new seals. I don't know if the factory one will heat the whole cab but the upgraded blower is much larger so it probably would. The new blower itself isn't much smaller than the blower in my quad cab dodge so I would say you'd be ok if you did the upgrade on it before installing. Part number for the fan from advance is 35334 and its only $25

I have more questions than answers.
If you do go with the bronco heater and the blower up grade be sure to use the gm blower cage also it is larger and you will need to open up the housing for it. The increase in CFM will be worth it. there is a write up on here on how to do it and part numbers. I think I would look for one with a larger heater core area. Maybe someone else has an thought on that.
