No, I'm a Porsche guy, but I love Corvettes. Now that GM are finally taking the Corvette seriously I look forward to buying one.
"Leading the charge" doesn't quite describe my feelings towards replacing the SBC. It's a great engine and I'd buy a C8 with the SBC, it's just that I'd rather own a C8 with a twin turbo DOHC V8. GM has taken their time developing this new V8 architecture and to combine their High Feature DOHC V6 experience with their SBC experience should make for a phenomenal engine.

Agreed it will likely have more issues, but that's because it's a new GM product. They'll get it sorted out just in time for the C9 EV.

They did that only to avoid massive fines in the EU. Marketing has you believing it is better. A large single cam7.2 would provide a far nicer driving experience over a high revving 4 cam 4.2. It will also be lighter and cheaper to produce and maintain. It however will not meet CAFE and we now follow what the Europeans were forced by government to do many years ago.

DOHC:
The first DOHC car was the 1912 Peugeot which won the French Grand Prix at Dieppe that year. This car was powered by a straight-4 engine designed by Ernest Henry under the guidance of the technically knowledgeable racing drivers Paul Zuccarelli and Georges Boillot. Boillot, who drove the winning car that year, won the French Grand Prix for Peugeot again in 1913 but was beaten in 1914 by the SOHC Mercedes
The discovery of this photo prompted us to search out other Peugeot photos and construction details, which will show you this brilliant dohc, four-valve four-cylinder engine designed by Boillot-Goux-Zuccarelli or “Les Charlatans” as they were called. Boillot and Goux were both racing drivers and Paolo Zuccarelli was a very talented practical engineer-mechanic. This engine that they created in 1912, established the dohc four-valve layout that is still in use to this day.

OHV:
The OHV engine was patented in 1902 (awarded 1904) by Buick's second chief engineer Eugene Richard, at the Buick Manufacturing Company, precursor to the Buick Motor Company. The world's first production overhead valve internal combustion engine was put into the first production Buick automobile, the 1904 Model B, which used a 2-cylinder Flat twin engine, with 2 valves in each head. The engine was designed by Marr and David Buick.

Since the OP brought up the upcoming Toyota Supra, I thought I'd share a little info on it.
2 mules have been seen in Carlsbad last weekend. They were both covered in netting as they were being driven along the beach. They were moving Southbound just after dawn.
Sorry, that's all I got.

I'm not sure why people refer to DOHC engine design as something modern while they refer to OHV (pushrod) engines as ancient. Both designs date back to the early 1900s & they're not separated by many years.

Thanks, that's an interesting comparison. What I've heard from the inside is that compared to the C7 the C8 performs at another level entirely, but what I'm looking forward to is the Corvette finally posessing mid-engine chassis dynamics, especially on turn in. That matters to me more than raw performance because honestly even the base Corvette Z51 outmatches my driving skills.
