you will have to make motor mounts (they might make them) may have to modify your floor pan, etc
just think if a part that is designed to fit usually has to be modified to fit correctly, something thats not designed to fit will probably require quite a bit of fabrication and "massaging"

Not true. motor mounts are being made for this swap as are headers to fit f-body and a-body cars with the ls-x engines. The transtunnel will have to be opened up. It not as big a deal as some make it out to be. Year One offers complete LS1 engine and transmission mounting kits for '67-69 and '70-81 Camaros. The kits include engine mounts, a transmission crossmember, and transmission mount. Kits are available for both 4L60-E automatic transmissions or T-56 six-speed transmissions and for cars using the OEM steering or Fourth-Gen F-body rack-and-pinion conversions. These kits should also work with Firebirds.

if you plan on using the factory a/c compressor location you will have to notch and rebox the frame (not a big deal). brp also makes a kit with mounts for an lsx engine into a second gen. some conversion kits out there requires you to mod the oil pan (brp doesn't). im using slightly modded 4th gen pacesetters for headers. you will need to get an f-body oil pan, windage tray, dipstick and tube as the gto pan is a front sump. you really need to go over to ls1tech.com and look in the conversions and hybrids section, theres alot of guys doing this kind of stuff and are very helpful. as far as i know nobody is yet making a rack and pinion setup for the second gen unless you go with an aftermarket subframe, which makes everything easier, but expensive
