heater specs

[86c20]

ok so i am making head way on geting heat back in my c20. new core rad water pump tstat (195) and no i didnt replace it all just for heat.

so i was thinking that alot of us seem to be haveing problems with heat and heaters so i would like some one with a good working system to take a few reading of temps. air temp out the defroster and floor vent. also the temp of the lines in and out of core.

i am thinking most of these truck run 195 stat. and the factory feed form the manifold and return to pump or rad.

i think if we can geet some specs on this it will help most of us alot. and help to find where are problem is faster.

also are there diff cores and blowers? see heavy duty and reg???
