Hey sharps.....the deluxe heater wont give you any more heat than the standard. I have had both in my 63. It originally came w/the deluxe setup and I converted to the standard heater to make room for the big block. In my opinion, the standard heater actually works better be recirculating. The fresh air (deluxe has to heat the ambient air which is normally cooler). The standard heater is recirculating. Now, this is just my opinion, but I didnt see the advantage of the deluxe heater for my application. If your standard heater isn't getting where you want on heat, Id replace the blower motor, clean out the core and maybe jump up the thermostat in the winter months. Chevy shows a winter/summer thermostat that are different temps.
