Please, a LT3 engine from mild say 6.2 480 HP to wild 7.0 cam in cam 570 HP maybe feasible as the last OHV harah and actually be used in the Vette and Camaro.

But a DOHC is a completely new engine for the Camaro and there is NO cost justification for it as the chassis is already traction limited. Plus I'm still not buying this smaller size DOHC engine that "fits" in the Camaro. Ford had decades of turkey SOHC and DOHC engine designs and arguably the latest 5.0 is not any "better" vs the LT1 / LT2 / LT5 / LT5. Ford (which should be no surprise) did what Yamaha has been doing for 50 years now, raise the intake port to make power NA and that means the engine gets EVEN BIGGER. So if GM goes with a "small" external dimension 5.5 DOHC it will have a extremely compromised port design and that means it will ONLY be good under FI where boost makes up for port flow (still got 4 valves and variable valves timing). But is makes for a shizznet NA engine.... just ask Ford going back to what 1994 ish??? Just about the time they contracted with Yamaha to build their SHO V6 and V8s, heck they could have hired me for pennies on the tens of thousands of dollars, I've been porting and racing Yamaha heads since the Toyota 2TG and 3TG engines (early 70s). You want a DOHC to flow? raise the port.... not "easy" on a V engine, especially if you now have a hot valley and the intake is now down by the fenderwells. Look at the new GM hot valley V engines, the intake manifold looks like an exhaust manifold (no surprise there) it must breath like an two pack a day 90 year old great grand pa, the engine has two turbos and in fact the smaller intake volume is not a bug it is a feature as the velocity hence response is REALLY good. But to pretend that you going to get this thing to breath like a Ferrari just because of the DOHC moniker belies a lack of engineering appreciation.

What part of a 5.0 Mustang's completely filled engine compartment don't you get????? I mean really? It has been going on 3 decades now that Ford's answer is UNWORKABLE given the Camaro and upto the C7's hood lines. Here a Ford: (caution GM folks as this may burn your eyes as well as dull your wits an no A/C and no warranty and a hideous hood bulge. )
