GM experimented with DOHC designs and stuck with cam-in-block for a reason. These reasons have been detailed again and again and again, but suffice it to say when you have a 450# motor complete from manifold to oil-pan that will make over 500 horsepower and pass emissions, you have a winner. Now consider that it will produce over 500 horses at the TIRES with exhaust and a mild cam and a tune.
Technology is great, and I am sure someday it will bring us an engine lighter than the LS-series that can produce more horsepower, but so far it has failed to do so within 2-300% of the cost of the most expensive LS-engines available.

in the 5.0's defence per your story if it's all price vs performance than a 5.0 that costs a fourth of an ls7 should only make a fourth the horsepower right?
the vk is good for 600hp in stock form same as an ls2/ls3 and they still cost twice as much at the yard. Titan motors are cheap, cheaper than a vq for that matter. if i wanted a car with an ls in it theres no point of putting it in a z go buy a corvette, if you want a car with a vk in it your SOL without a swap, i believe swaps should be done with motors from the same make unless none are available
