I was just reading an article on the LT1 for the C7 (anything to distract me from work).
Anyway, why is it whenever it's mentioned that the cam is in the block, they always have to mention that this is an outdated technology? Why are OHC engines regarded as the best engines out there? The article compared the new LT1 to BMW's 4.4 liter V8 and found that the LT1 is only 465 lb compared to the BMW's 503 lb engine. It's also 5 inches shorter in height and makes 50 more hp. So I guess I just don't know why the press has to bash the fact that it only has two valves per cylinder and that the cam is still in the block every single time they talk about the LT1.
My thought is that if OHC were the norm and someone stuffed the cam in the block, it would be regarded as great as it has less rotating mass, is lighter, more cost effective, etc.
The only advantage I can see an OHC configuration having is that you can adjust the intake valve timing independently of the exhaust cam. Maybe you can squeeze extra horses with this set up but I don't think the Corvette is hurting for more hp as much as it is for reduced weight and low engine height.
Thoughts?
