Well, since our government has adopted stringent CAFE requirements, gas mileage matters. Performance cars are not immune....

I see where you are coming from, except there is no replacement for displacement. Cars with big engines just drive nicer, so, yes, I am happy it is a 6.2L. I would have liked a 7.0L even more.

All I was trying to point out, as a layman, was that the global consensus appears to be that the DOHC solution for most race and road cars (and bikes for that matter) is the more appropriate choice. Are they all wrong? I have nothing against the OHV engine or GM or anything else, but the points I made about the majority approach were true and valid. Also, the points I made about global warming and the different opinions and approaches that governments take to address them (technical restrictions and taxation) are directly related to the design goals of the engine manufacturers. The US has an approach that is less stringent than they have in Europe specifically because of the opinions and views of its politicians.

Having others intentionally misinterpret my arguments, and attempt to disregard or not even read them is pretty offensive to me, no matter who the poster is. I did not disrespect or attempt to belittle JVP but for some reason he chose to take that approach with me, when I called him on it, he took the typically bully retort of calling me out for disrespecting him. Really, I genuinely appreciate your sympathy, it really does mean to world to me.

At the end of the day, I stand by my comments on OHV vs DOHC, not because I technically can discuss which is or isn't better, but because most manufacturers take that route. If you can show me that the majority of manufacturers of auto engines favor the OHV over the DOHC, go ahead.

In reality, cam-in-block engines are newer than OHC engines and they offer a number of weight and packaging advantages over DOHC engines, but the non-engineering public thinks OHC is “cooler” and “more relevant”, so from a marketing perspective, I agree with you; however, to keep the base C8 reasonably priced, using an LT engine gives great corporate economy of scale and the LT engines are strong and reliable and GM has kept them completely up-to-date technologically.

I suspect the higher-end C8s will have all the bells-and -whistles—dohc, TT, hybrid. all wheel drive, probably 4-wheel steering, low speed front lift, active aero—and will cost a lot more but will be the tech leaders GM wants them to be. But we can all buy and brag about them to our Euro sportscar friends....after we blow by them at the track. 😜

P.S. If GM really wants to throw a touchdown here, what they should do is ditch double overhead cams, 4V, and have direct pneumatic 4 valve actuation like Renault developed for F1 several years ago and put this on an ultra high-end “super” Zora. The pneumatic valve actuation enabled these engines to turn around 22,000 RPM before the FIA decided they needed to cut costs and reduce RPM range. That would be a technological bragging point that no other street car in the world has, as far as I know. Build a 10,000 rpm street engine!
