There was nothing wrong with pushrods when they first came into use as man attempted to outrun dinosaurs. But like I said, build an engine with pushrods, and build the same engine with DOHC, and tell me which makes more power. It'll be the DOHC every time. I don't dislike the corvette because I think its slow, I dislike it because it could have been faster. I understand GM cuts costs like every major car company must do to make money, doesn't mean I have to agree with it.
Either way I know you're just jealous that my engine has DOHC and 5 valves per cylinder and outputs more than 12 BHP/L
