You can definitely run an AC with an LS. If you're using the f-body pulley you'll just have to notch the k member and get the adapter hoses from hawks motorsports.
I did my v6 to v8 swap. She's running and driving good. Thanks again for sharing this info. The fishing line trick worked perfectly for the motor mounts. The battery is on the driver's side of the v6. I was able to leave mine in the same place. The other side has the charcoal filter and the v6 airbox. The piece you are unsure of is part of the emissions. It bolts to the v6 manifold. If you can't figure something out, I still have a complete v6 parts car we can reference if needed.
I put a Lq4 with a 5 speed in my 92 I relocated the battery back behind passenger seat I removed all the wires hell I removed everything from the car except the glass I’m. Almost ready to start driving it
for the por 15 just poke 2 screw driver size holes on the lid to pour it out then seal it with tape . that way you dont have to tear the lid apart to open it.
I'm strainin' my brain but I dont remember. I think most of work was done with a wire wheel and Purple Power spray cleaner. Rust-Oleum covers alot and this ain't no prize winner.
