Well I am in the ac connection business this week on my truck. Doing a ls swap using all org. ac parts but compressor and condenser. Compressor will be a Sandon 508 and the condenser is out of a 2001 firebird same as my engine. Here is the question. The firebird had the condenser with the large hose on the bottom .My ac man who I really respect says the large hose should always be on the top . I checked three different Firebirds with factory ac and they all have the large hose on bottom. My ac guy says if I put the large hose on bottom I will get a air hammer type noise from the compressor. Anyone want to way in on this. Very troubled on who to listen to.
