Re: Stock air conditioning with LS swap
Are you dead set on keeping the Expansion valve/ POA valve/ Receiver Dryer system? It would be cheaper & easier to replace the Evaporator core with a fixed orifice style evaporator (Ive found 77 Olds 98 evaporators fit the best) & run a Accumulator & Orifice tube.
What year/make/model did your LS come out of? GM put the high side trinary in different places, sometimes in the discharge side, sometimes in the liquid line.
