LS Swap AC Compressor Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Scarface · 08-09-2017, 11:25 AM

I have a 79 C10 with a 5.3 LS Swap and I want to mount the AC Compressor down low in the factory position but the motor mount is in the way. I know it can be modified to make it fit. I just wanted to ask and see if anyone has installed the Trans-Dapt Performance Engine Swap Motor Mounts 4205

Thanks

and the frame needs cut/modifyed also and not just a little.

I was hoping that it didn't need much if any cut on the frame so maybe I don't want to do this

Take a look over at the lsx swap section and you might find what you're looking for. I have an ls1 with fbody accessories so I can't really answer your question.

I personally have been looking at passenger side high mount Sanden compressor options. The compressor is way more effiecent and is smaller then the R4 style

I put an LS in my son's 84 truck. I notched the frame where the compressor lines exit.
For the motor mount, I pulled the frame mount off the truck and extended it a little but. Then redrilled the motor mount holes. Like was said earlier, lots of info in the LS swap forum on this site.

I would also install a trianary switch for the fans unless you have your computer sending input to them from the AC control.

If you need pics just PM me and ill text em to you.

I still use the factory condenser core, accumulator and evap core. Truck blows frost out the vents.

I have the sanden compressor that can with the old air setup and everything is done with the exception of mounting this compressor. Trying to run it low on its own belt since I have a d1sc procharger and the belt it already pretty long
