It can be done.

Several small modifications are needed but no cutting of the floor at all.

When it is all said and done you will need to check your ground clearance.

How do the driveline angles look?

Andrew

​​Excellent angle.. 3 degrees tilt angle on the transmission. Once I install the drive shaft I will post photos.

The CTS-V transmission oil pan is almost half the depth of the trucks oil pans. When swapping the oil pan also get the transmission fluid filter (the trucks filter is too long). The 6L80 has to be installed as close to the floor as possible ( I have 1cm of clearance at the point where the tranny meets the bell housing to the cars floor).
My new pan has 1" less clearance to the ground than my other 700r4 and 4L65e Camaros.

Three degrees relative to what? Chassis? Earth?

The transmission is 3 degrees down relative to the leveled subframe. Once I complete the reassembly of the car, I will verify and calculate my transmission and pinion angles, I sure don't want vibration problems or premature wearing of the pinion bearings. It is important to have forums like LS1Tech to share knowledge and experiences with everyone interested in building cars. I say that is specially true for beginners or those who simply look for a helping hand with their projects. I have been building hot rods for years, even won several shows like Best Camaro at Supper Chevy and Street Machine at Goodguys. So you can "lol and tff" all you want to me, but please think for a few seconds before you lol some young person looking to start their first cool project out of the forum "senior tech".

I had to use the G8 6L80 oil pan with my install. So maybe the CTS-V pan is the same or similar. Also the 69 Camaro transmission tunnel may have more room than the one in my 1965 Buick Skylark. I think by 1969 transmissions such as the 4L80 were a used quite a bit and they needed the extra clearance for them. That would make fitting in a 6L80 a little easier than what I had to do by replacing the whole tunnel.

I was merely asking a question, and a legitimate one at that. Saying 3 degrees down without a reference point is meaningless. Now that you've clarified a reference point, that makes sense and is useful to anyone that happens to stumble across this thread in the future.

Depending on your rear ride height, the current angle may or may not be optimal, but you'll know more when the driveshaft is in, or when you approximate the angle of the driveshaft.

From my 12 completed engine transmission swaps I gave you my opinion. My opinion comes from hands on experience not from "Googled photos off the internet". Best of luck with your project. Please take the time to post on your progress..

"The whole tunnel" never needs replaced.

There are several ways to do things. Sometimes, sticking with stock driveline length matters; BTDT. There are enough guys afraid to cut their floor to build a bridge to Hawaii. Expanding existing metal is seldom considered, and could be.

Good luck with the LOLs.

I am staying tuned for the driveline angle notes.

Mr. G

What brand mounts and cross member did you go with? I'm in the early stages of doing a similar swap and would like to use your build as reference. Thank you!!!

Hello. I'm using the ICT Billet engine adapter plates (plus SBC energy suspension). Hooker 12627 LS1 transmission cross member with and adapter I made to fit the 6L80. In my other posts I got pictures showing my progress. What is more specific to make my set up fit in the car is the changes I made to the subframe and the subframe engine towers. Dropping the engine into the subframe is what makes everything fit. The 6L80 oil pan was change to the Cadillac oil pan to gain ground clearance. I'm now waiting on Holley LT1 oil pan to finish my installation. The Corvette, Camaro, or Moroso oil pans are not ideal for me since I dropped the engine. The Holley pan will give me the best ground clearance and also allow me to use stock steering components. If I'm wrong about the Holley oil pan I will be force to look at Rack & Pinion options. More to follow soon.

I am pretty sure that the Holley oil pan will allow you to use stock steering components...but don't quote me on that...LOL

I am pretty sure that it is shipping...but maybe in limited quantities.

Mr. G

I can't load the pics. I think there is something wrong with the link. Keep me posted when you get the pan to see if it actually worked. Where are you located?
