Chevy recently lumped the Camaro, Corvette and SS sedan into a new Performance section on their website that also includes crate engines, transmissions, other components (i.e. carburetors and superchargers) and Camaro-specific parts.
Here's some of the engines they have available; the full selection includes engines like the C6 ZR1's LS9 and the 770-HP LSX454R, and there are also Connect & Cruise powertrains with everything you need. I thought that a crate LSA would cost more than an LS7 since it's more powerful and, as I understand it, is a downgraded version of the LS9, but I found out that a crate LS7 is more expensive when I was poking around in this section.
The Camaro section talks about the COPO Camaro and body-in-white kits. It also lists individual parts from the 1LE, ZL1 and Z/28 (as well as the COPO Camaro's hood) that you can mix-and-match with the standard V6 and SS Camaros, in addition to other mods.
Obviously, selling crate engines and such isn't a new thing and GM had website(s) for this already, but I thought it was cool how Chevy put it up front on their website alongside their bread-and-butter operations. The 2013 Chevrolet Performance Catalog can be found here.
Thanks for sharing this to the FP, Michael!
