They have their place. But corvette has always been a budget sports car. It's far cheaper to punch out a 5.3 to 6.2 to make the horse power than go dohc to rev it to 8500 to make the same HP. The low end torque is also far more enjoyable. This move by GM is all about cafe, not what's better.
DOHC motor using LS7 block, same dimensions as LS7 and lower.And 750hp NA. All the torque u would want.

I beg to differ. This move is about creating an international HALO car for General Motors. It is GM telling the world that they are back in a big way! And that their sports car is equal to the best available at 1/2 to 1/3rd the price.
An OHV engine will just not get the job done!

I'm told one reason the current small block has the same bore spacing as the one in my '56 is the billions spent on that plant for precise tooling and automation! The plant has evolved to being capable of making truck engines and high hp ones for cars.
Once trucks go over to diesels to meet corporate cafe that plant will probably make the 650 hp 3.5 Liter V6 as the high performance engine future!
Heck if Ford can get 647 Chevy should be able to get 3 more!

Imagine the response if Ferrari, Lamborghini, MB, etc. announced they were dumping DOHC and going to pushrods...
The LT4's SC isn't particularly expensive...nor is the Superchargers Ford uses.

An OHV engine will just not get the job done, i.e. the job being the creation of an INTERNATIONAL halo car! Sure, an OHV engine might fly in the US, but it will not hack it in the rest of the world. This is precisely why GM is creating the new DOHC engines.

My dad bought a brand new 69 Corvette out of college as he was going into Naval Flight Training. The only new car he ever owned. The Corvette was always attainable by blue collar workers. I don't see that being the case for much longer if people get their way on transforming the car into something else.

No argument from me that more than a few Chevy dealers need to up their servicing skills re our Corvettes.
At the same time, just as we do not always go to the closest restaurant, hire the financial advisor in nearest proximity to our work/homes, choose a doctor based on how close he/she is from us, a hell of a lot of responsibility does lie on us!
Similar to how we choose the above, we need to research/investigate/choose prior to our taking our Corvettes in to be serviced at any dealership.
I now drive by a Chevy dealer who was 4 miles away (now closed), drive by a large one about 20 miles away, and choose to drive 38 miles each way to an outstanding Chevy dealership. The Corvette Tech there is outstanding.
We need to be an integral part of the choosing the right dealership for our Corvettes — and we all also hope that GM takes internal steps to improve the skills for all dealers they certify as being Corvette maintenance/repair certified.

Regarding engine placement, the operative terms are, as always, front, mid and rear!
I suppose that if someone really wanted to coin a valid "front mid" term they could change the current definition from "engine mass behind the front axle" to "engine mass within one foot of the center of the wheelbase". However, does anyone really care? A mid engine car is, and always will be superior to any "front" variation for a sports car. Simple physics!
Please note - "superior" when all other factors are equivalent.
