Default LS Swap questions

First off I'm sorry if this is in the wrong place as this is my first time posting.

I'm doing an LS swap in my 69 Chevelle and was trying to figure out if the engine accessories from an 03 GTO would work for this swap, I havent had any luck finding any information on this and any information you guys can provide will help, thanks in advance.

Not sure exactly how the GTO accessory drive compares to the F Body, from looking at pictures I think they are the same. The F body has the issue of the alternator and the steering box trying to occupy the same spot. My swap is an LS1 into a 70 Chevelle. I filed a little on both, more on the front fins of the alternator. Depends on where you end up placing the motor. Mine is set about as far back as I could get it. Some guys will use a relocation bracket and just move the alternator up. Hope that helps.

Also if you plan on using the AC compressor in the stock GTO location you will have to notch the crossmember. Not a big deal, just some extra welding.

I think you may mean '04 GTO, right? There wasn't any GTO in '03. The '04 GTO is an LS1, whereas the '05 and '06 GTO's used LS2's.

what exactly do you have for engine and front stuff? Im sure truck stuff works by changing steering pulley size if its a issue. I had to on 5.3 swap with truck front stuff as steering box/ steering pulley was problem on my 76 skylark. I have seen on here vette stuff works with chevelles.

I'm installing an LS3/4L60E in a 1968 Chevelle. I used the GM Corvette assy drive kit. Clears the steering box nicely. I used the Holley 302-2 oil pan, as it's only 1.25" inches deep at the front and clears the inner tie rods at full steering lock. The Energy Suspension LS swap mounts locate the bellhousing 1.25" forward of stock, this is the only way to not have to cut the trans tunnel. Plus it gets the engine lower than any other mount kits. The lower the engine, the better the front u-joint angle.
