heat issue

i have an 1985 chevy k2500 with a small block 350... im only getting luke warm air... blend door is workin properly.. heater core is new so it is not plugged up...i do have alarge radiator in it due to it being a plow truck.. have the preasure hose comin off the intake manifold and the return to the radiator.. should i move the return to the water pump for better flow? truck is runnin 190 all day... 215 if io put plow all the way up... thoughts????

i know this sounds like a dumb question but did you check to see how much water is actually flowing through the line might be the out let line from the intake is plugged up due to galvanic reaction steel and aluminum dont get along or check to see if the water pump is working properly

no that is something i didnt do.. intake is stock and pipe fitting is steel.. so i wouldnt think of a restriction.. but it is still possible.. hose gets hot all the way to core.. and return one is hot also..slight difference in temp..
