Hey out there has any body put a 400-455 in a 64 riv and if you have did you have ac.My problem is that after getting all set in there and mocked up the original POA valve and line to the evap core(the line I believe is part of the evap core) is hitting the back of the right cylinder head and valve cover.Does any body have a solution like getting rid of the poa valve and going to a different system such as expansion valve or orfice tube style.I may be converting the ac from a A6 compressor to a new style dont no yet.Any help would be greatly appreciated.I would like to hear any stories from this type of swap if anyone has one.Thanks
