I just figured going in the LS3 would win based on it being on the market longer and having better aftermarket support and giving up over a liter in displacement. But the import guy in me just wanted the Coyote to have a really good showing with its DOHC 4v heads and higher redline. But the LS3 is just tough to beat.
Years back the flat head Ford was the engine of choice for all hot rodders. Ford refused to get with the program with OHV and by the time they did the SBC took over and never lost their standing as the engine of choice.
Now Chevy is hanging on to the pushrod V-8 when everybody else has moved on to OHC engines.
How much longer can Chevy stick with last century's technology?
When everything being equal like cubic inches, the OHC engine wins every time.
It's all in breathing and the four valve head wins every time.

Why fix something that isn't broke?
I wish I still had my '05 GTO with the LS2. Plenty of power and very easy to work on.
They were both invented around the same time...OHC vs OHV. So really, they are both "last century's technology."
Chevy knows how to build OHC engines, as they have used several of them along side the SBC and continue to do so today.
I agree with that heck today a Modren small block 16-OHV V-8 is in all GM's top Vehicles from their Truck line up and Full-Size SUV's to their flagship sports car Corvette Z06 and Luxury Car Cadillac CTS-V and Escalade SUV.

Exactly and they have DOHC high feature V6s and DOHC Ecotecs I4s in everything else. Including high power turbos in the ATS-V and Cadillac V sports. Although Northstar is gone, Im pretty sure a DOHC V8 will resurface in a Cadillac someday soon.

to expand on Tourian's post...
OHC is a subset of the OHV family, as OHV stands for Over Head Valve (as opposed to Flathead or L head design). OHC still has the valve Over Head, it's just that the cams are up there, too.
OHC engines have been around since 1918. The first American DOHC engines were in the '32 Stutz and Deusenbergs, with 32 valve DOHC 8 cyl engines. In fact, the pushrod OHV V8 was invented as the high tech, compact, lower cost answer to the big OHC engines. Advanced metallurgy allowed for a compact thinwall V8 that made more power for less money, taking up less physical space.
So both the OHC and pushrod OHV V8s are "last century's technology." The ONLY advances in both are metallurgy and production tolerances, and in electronic engine management. The Coyote is a smaller displacement engine, but physically MUCH larger and heavier than the compact pushrod GM LS family of engines.

The thing is that it works.
If one looks a high performance German/ Italian engines with all the newest fangled tech, they just don't last.
