For sure, GM has (and still is) extracting incredible amounts of power and efficiency from pushrod motors, the LS2 being one of them.
All I wanted to get across is how innovative and significant the C4 ZR1 motor was when it was released. For that time period is was an incredible piece of machinery

I'm almost thinking that getting the same horsepower out of a much simpler and less expensive engine is an even greater accomplishment than getting it out of the LT5 was. Just rambling here....

Don't get me wrong...it certainly was...I wouldn't dispute that. But $30,000 back then was like having a ZR1 today with a $100,000 engine option. It was indeed innovative, but it was so complicated that GM wasn't comfortable assembling it and had to farm out the assembly to Mercury Marine. I know that most of those ZR1s are sitting around being polished and shown at car shows, but I'll bet that repairs are extremely expensive also...especially on the ones that have seen 100K miles. At the end, a crate LS engine is around $6,000...imagine what a rebuild would cost on the LT5...I'm assuming there aren't any crates around but seems like at least $30K if they were sitting on a shelf somewhere.

With all that being said, I doubt we'll see a DOHC engine in the C7 ZR1 based on what they have achieved with a standard push rod motor.

when my 05 LS2 was stock with stock tire it ran almost a full second quicker at 12.40 versus the typical ZR1's that I raced back in the day that ran 13.20 too 13.30's.not even close!!!!

I have an LS3 coupe. It is stout, but I wish it had more top end.

If GM has both LSx and dohc v8's at the same time, it will just end up being the same problem as with the LT5 rarity. They need economy of scale like the LS since they come in trucks and camaros. This is what will make the platform more successful.

The C8 Corvette will have a front engine with 525 Horsepower and will be a upgraded styling and mechanical version of the classical Corvette design. The midengine "Corvette" is not a Corvette at all but a new car altogether built to compete with the Ford GT40 and other high tech machines. It will use all the ultra tech materials and designs that are too costly for general production. The DOHC V8 will produce 725 horsepower and latter versions will approach the 1,000 horsepower mark, both will be supercharged. Production for the first year will be limited to 500 units and expanded as demand dictates. The name for the new ultra tech machine is still being discussed but will start with the letter "C" as do other Chevy machines.

No real reason for a DOHC unless you are trying to make power with a displacement limit. Packaging and weight are horrible compared to today's design. I'd be more inclined to put turbos on an LT4 with more displacement. Lots more power under the curve.

unless anyone who has posted here works at GM or a supplier on the upcoming DOHC engine or next generation vehicles, all the information here is purely SPECULATION, rumor, and hypothetical......
sorry to burst your bubbles........... if GM wanted you to know, or if you had the need to know, you would have the information already..........
sorry for the rant, but is is getting pretty common and tiring of seeing these trivial, misinformed, theorized topics run any longer than one or two posts, NOT pages.............................

Unfortunately, it will not happen. The market for these cars is too slim. There are not enough buyers to support two distinctly different, very costly platforms.
If the mid-engine Vette is a hit, with no issues that cannot be fixed, the front-engine Vette will be gone forever.
