Could someone please post pics showing where they notched the frame on a g-Body car for the A/C compressor & for the stock LS1 oil pan to clear. Thanks!

Do you have access to a truck oil pan, one can be had for pretty cheap, or a retro one, i think those are around $250 though, with the truck one you shouldnt have an issue...

or you will have to notch the pan, I wouldnt notch the frame for the oil pan, but anyhow.. my bro and I had to notch the frame a little in a friends cutlass for the ac, but I dont know if I have any picts, I will check when i get home, we notched it and then boxed it in, although prob didnt have to box it as only a very small section was cut out to clear the pulley and belt...

I dont know what your budget is, but you can also relocate the ac to the top using a bracket from kwik performance...

Here is a picture of the cross member knotch. It's not a good pic, but the only one I have.

My plan was to not cut anything but it looks like im going to have to go the cutting route. I have been searching all the LS forums to see if there was a set of mounts/adapter plates/ headers that i could use that will have everything to clear but I found nothing. If you know of a set that will clear everything please let me know...I was looking at the kwik brackets but that would be way out of my budget so I will have to do what I have to do to get the engine to fit with the a/c compressor because it gets too hot here in the summer. Are there any high mount A/C brackets that I can use off another vehicle with this engine? I have a truck oil pan on my engine now but im not going to use because it hangs too low. I was thinking about getting the LH8 pan that doesn't hang as low but if I'm going to cut the frame any i might as well get the crossmember cut so i can get a pan that will not hang below it.

I have the Mast oil pan, but was going to go the CTS-V route, I have heard alot have used it without having to notch/cut anything.

cant find the ones i took on my computer, but have you sat the motor in yet? cause you could take the compressor off, sit the motor in place and marked the frame where you need to notch it, then just notch it out.. the main area that needs clearance is around the pulley, to get the belt on and off and to clearance for little movement

From what I've read the only pans that clear and are equal or above the crossmember without notching is the Holley and Mast pan. I'll be finding out in a few weeks how true this is with the holley

And I will know with the Mast.

the pic by mcss is about how I cut mine back in 02' for F-body pan. I also notched & reboxed one spot by the idler arm & cut 1 small notch in crossmember for factory location ac, Which is now a sanden w BRP mount.

I cut roughly 2 inches deep,guessed at the length and flipped the piece that i cut out,and re welded it back in.

I just happened to click on this post and could not believe it when i read that my old truck pan could be the solution to a problem. i am putting a 5.3 in my 55 Belair and had to get an LH8 pan and have the truck one laying on the driveway. I was going to haul it to the junkyard but will make anyone who needs it a great deal, $65 including shipping. Just pm me-Bill

I notched mine 10" wide and right at 2" deep. I am running a 5.3 with F-body oil pan. Basically took a metal cutting hole saw at both ends, and then cut the length out between the holes at the ends with a metal cutting sawzall.
