I picked up one of the Youngs F-body motorsports brackets designed for the LS1 engine so you can use a standard round AC compressor used on GM cars and trucks thorughout the 80’s and early 90’s. I'm installing this on my LSx engine that's going in my 1976 Camaro..

The price on their website is $299 + shipping and there is no way I would have payed that much for this kit. I ended up getting it from a member on another forum for quite a bit less still in the box.
Here’s what you get:

1. Rear Bracket (1)
2. Front Bracket (1)
3. 1” deep spacer for 10 x 1.5 bolts (3)
4. 3” deep spacer for 10 x 1.5mm bolts(2)
5. 10 x 1.5 x 50mm bolt (2)
6. 10 x 1.5 x 100mm bolt (3)
7. 10 x 1.5 x 130mm bolt (2)
8. 10x 1.5 lock nuts (3)
9. Idler pully spacer (1) – this was a custom machined part
10. 3/8” washer for idler pulley (1)
11. Belt – Kelly springfield brand part # 6K922 (1)
12. Idler Pulley – Dayco brand part # 89007 (2)

 

First thing I did was swap out the stock pulley on the tensioner for the dayco #89007 supplied in the kit. I had to remove it while I was installing the brackets

 

I then position the brackets using the 1” and 3” spacers , two 10 x 1.5 x 130mm bolts, and one of the 10 x 1.5 x 50mm bolts as shown in the picture below.




Here is a pic of the ac compressor installed, I actually had to drill a hole for the stationary tensioner. The hole was missing, but was there in the instructions??

I mounted the tensioner with the last 10 x 1.5 x 50mm bolt, lock nut, washer and machine spacer.

 

I Use the 10 x 1.5 x 100mm bolts and last three locknuts to secure the compressor…one bolt required me removing the passengers valve cover to get it in.




Finished product..looks pretty good..I’m not sure if I got that belt on right, it wasn’t shown in the instructions…but it “looks” right. The only complaint I have is having to drill the hole for the stationary tensioner since it was missing....if I paid $299 for this kit I would have been pissed. And the instructions sucked too....most of it was crudely hand drawn diagrams and the actual pictures where bad scans (too dark) and you can't see what's going on.

 

so have you don e any of the wiring for the ac yet? nice write up, its good to see pics of this kinda thing, especially if their directions suck.

 

No wiring on the AC yet, it should be simple enough because the compressors shares a similar design as the long pump that came in the car as far as wiring goes.

3rd gen guys it should be plug and play...

 

Let us know when you get it running. What I've always heard about the Young's kit (FBODYMotorsports) is that the belt isn't aligned and comes off.

 

I think I read that before, all I can say is that the ac compressor "looks" like it is in line with the other pullies.

If the belt isn't lined up you can always shim or remove some from the rear spacers to get it aligned. People have to do that with aftermarket water pumps all the time.

 

I also priced the belt and pullies..the 89007 pulley is $12.94 each at rockauto and the belt is around $13.

The bolts and spacers have to be around $20 - 25 (if THAT much). For a grand total of $60 in parts less the brackets. I'm not seeing the justification of marking this kit up to $299 on the website. Unless it's a matter of tapping into a market with very little competition.

 

Yeah just wish some one would produce a template, or a kit that didn't cost as much as a longblock lol

 

I've got a corvette that I may drop a LS1 in if all goes well with my camaro. It uses the same compressor...I traced the brackets out so when i'm ready I'm going to get a machine shop to cut them out for me.

 

Send me a scaled scan of the tracing and ill draw/dimension the brackets for everyone to use

Unrelated bit, but what oil pan did you use and howd it fit the 2nd gen subframe (K-member). Ive got a buddy considering it

 

Ok,

On the 2nd gen, you can use the the standard type adapter mounts, stock clamshell engine brackets and frame mounts and a f-body oil pan.....it'll clear just fine. It's about 1/4" from the k-member but its ok.
