Are you certain its the blower that sucks?
Is it the air speed?
Temperature?
Or lack of temp or fan range?
The upgrade is a heater motor 1312 for a '73 Chevy Blazer with a 350 and air conditioning. Less than $30. You will need to cut the hole in the fire wall to 3.25 in.

I upgraded my ‘80 CJ7 with the 1973 blazer blower motor. The previous reply from JPNinPA is right in what he’s saying, and it will definitely increase the amount of hot air pushed through the heating ducts. I would go ahead and change the heater core as well, since it all has to come out anyway. A dremmel with a coarse cutting stone worked great for opening the blower motor hole in the fire wall.
