That is very difficult to do while meeting emissions, which is why so few engines accomplish it.

Larger production numbers don't help an engine meet emissions requirements. If anything, a low volume car has an advantage because I think there are exemptions available for ultra-low volume cars. But both the Z06 and the GT350 will be grossly exceeding the production cap (I think its less than 30 cars over the entire production run) so that exemption doesn't factor in.
I'm sad Ford will have his 'LS7' equivalent while GM wont have anything like it anymore. Ford will get my money, maybe..unless I chose a stock LT1 SS with a ****ing cam!! That is going to be a badass car for the money!

I'm a N/A fan, too bad they have to go the FI route now. I mean its the 1st year, they are going to fix the issue or let the customers do it (speed shop). Its still a bargain with no option, but its weird that a N/A car with less HP and same weight kill it.

Yeah old ZR1 kicked some serious ass at the time.

The LS7 remains the ultimate performance car for the money IMO.
