Gto engine and trans

Will a Gtos drivetrain, accessories, etc work for an ls conversion?

The GTO shifter is in a set back position. I think an f body shifter can be swapped. The output yoke needs to be changed too.
Check over at LS1tech manual trans section for details.

Maybe ask how easy instead. I am not an expert on the GTO version LS, but believe the low mount A/C and Alt will not work as-is. The exhaust manifolds are too wide at their exit point unless angle milled to bring them in closer to the block. The GTO T56 shifter location is further to the rear than the stock C3. All of these problems can be worked out - it just depends on if you want to make it work.
Edit - The oil pan will not work

Also a/c is not an issue for me-don't need it. But the alternator and exhaust manifolds will be.

The GTO alt/PS are the same as F body so they should be fine. The GTO has an IRS which is why the odd output yoke on the manual trans. Not sure what they use on the GTO 4L60e.
I've got a set of GTO manifolds, I don't think they'll clear the engine mount horns. But you can find 02 Z06 manifolds cheap, they flow well, they fit.
F body or corvette oil pan will be needed.

I think the auto is a 4L65e - a variation of the 700r4 that people have used in the C3. I picked up some GTO manifolds and found they were too wide. I am using them on something else, and picked up Corvette manifolds. I have read where people angle milled the GTO manifold head flanges to bring them in closer to the block. A F body or Corvette oil pan is usually needed. The GTO alternator mount -I am not sure. The A/C will not work, and I am guessing the alternator (because it is in a similar position) will also be a problem.
Edit -Gary types faster than I do!

Silly me, I was hoping to see a Ram Air IV with an M-22 going in.

I have an LS3 with 2010 and up camaro exhaust manifolds and cats, they clear just fine. I also have the CTS-V accesory drive, with a KWIK ac bracket, all clears. The low mount alternator has about an inch from the top of the lower control arm bracket. Motor will have to be lifted to replace it. I used Jegs ls swap mount adapters for stock location. They are very heavy duty. Stock 2010 camaro oil pan will not clear power steering ram with these mounts. I think the GTO is very close to the CTS-V accessory drive.

Will I have to modify the driveshaft or output yoke? What else do I need to make this swap or does that sound about right?

I was Just indicating what fit with my engine, I have seen the camaro manifolds cheap on ebay, other members have used different combinations with their ls swaps. As to the accessory drive, I used this.

I believe this is very similar to the GTO system, therefore the GTO parts you have should fit, with the exception of the A/C compressor. I am installing the Vintage air with the KWIK bracket. Nice piece. http://www.kwikperf.com/lsx_ac.html.
