LSx A/C Compressor in the Stock Location

[dec010974]

Hello to all. Like the thread title says. Using Stock LSx components, and the stock 1973-1987 C10 Frame and motor mounts, you can run your LSx, stock A/C Compressor, with the stock A/C backet in the stock location.

Visual Picture so you get the idea

Thanks for posting, trying to get mine set now. Don't have the 73-87 2wd engine stands, waiting on a 4x4 set ftom a 76, that are built slightly different but I hope puts the mounts in the same position. Post a photo if you can.

I can't help but for those that can what ls motor are you referring to? Is it a truck motor like a 5.3 or a 5.7 from a car? I hear reference to the lsX but thought that was an aftermarket block or just a generic term. A little info on year and motor will help.

Sorry for the delay. For some reason it’s very hard for me to post pics. I hope this works.

You can use any adapter plates along with the stock a/c compressor and the stock a/c bracket. The a/c bracket will need to modified, cut depending on how close it is to the motor mounts.

I hope this helps

For those who don’t know, all LS engines are basically the same even thought some may have different displacements. All the parts are interchangeable. I use the term “LSX” to cover car and truck engines, gen 3 and gen 4. This covers LS engines from 1997 corvette and 1999 GM trucks to 2014 GM cars and trucks. I hope I covered everything

Most engine mount adapter plates will require modification of either the adapter plate or a/c bracket. Unless you use the Hooker Blackheart system which approaches engine mounting in a reverse fashion. Hooker retains the LS engine mount (F body type) and handles the offset via a new set of perches or stands. I like the fact that it keeps the engine low and thus proper driveline angles easier to achieve.

Very nice. I was hoping to keep it down there. Now the question is can the stock compressor be used with an aftermarket system such as vintage air?

[dec010974]

@Joemomma1 i dont see why not.

Thanks for getting the photos up, I found the correct mounts, like you posted. Looks like you have the Speed engineering headers also, I did a test fit they seem to fit very good.

The factory F-body bracket on my LS1 would not fit in the frame
I'm using a Sanden compressor with Alan Grove bracket
Plenty of clearance at the frame

The tejas steelworks motor mount brackets allow you to use the factory a/c placement.

There’s plenty of ways to skin a cat. On my truck, LSx builds, I try to use stock parts. There’s no need to buy aftermarket parts when you can spend time and ingenuity to make the swaps work. Most of the us have these parts lying around in our garage. I can go to any parts store and say “ lemme get a compressor for a 2001 Chevy Tahoe”. Who has an extra sanden compressor lying around.

Which headers did you use on the 68 and do you have to do any mods to the drive shaft?

Do you have pics of it installed in your truck and i would have more questions for you.

This is an old thread.

The Tejas steelworks work on the squarebody trucks for factory AC compressor retention. Not sure about earlier models. I've had a few sets on K5's and I think as long as you are using a factory clamshell pedastal for 67 and later, they should fit but not sure if there is any difference between the front part of the frame and crossmember that would cause extra interference. If you want an idea how the fit on squarebodies you can go to his facebook group and inevetibly someone will post pictures or they definitely already have with how proud they are for having mounted them. The cautionary tale on the mounts though is they move the motor forwards in the engine bay about 2 inches. Not in issue if you are already going with custom driveshafts and a custom trans mount but just better you know in advance. It will also affect cooling fan or water pump pulley to radiator clearance depending on your fan and radiator selections. If you are going with an aftermarket AC system I would just get the alan groves bracket because someone like vintage doesn't really like you using the gm unit. You can but they state it will affect warranty claims and they also claim it doesn't cool as well as their Sanden style compressor. I suspect if you have a metal saw, welder, and patience you could make your own bracket like Ugly Truck Experience off youtube channel. It's something they show you how they made, plus sell. Just some feedback to get you pointed in the right direction!

I have an 1987 silverado and used stock 2001 ish compressor and used compressor manifold adapter blocks to go from comprssor to hose. I had to put a notch to clear the suction a/c line, but other than that, yes, it fits.
