I don't know when GM will break away from OHV V8's, but I feel it is somewhat on topic to point out the LT4's deficiencies as not a totally improved product while we all wish for something a little more exotic. My biggest point is the fact that there were a ton of you tube vids from week one that showed just about everything handing the new Z06's azz to it on roll races. Then came the GM apologists etc...
My take is that GM is holding back...way back... the engine only has a 1.75l supercharger that has to spin faster than the previous ZR1's LS9 unit which was 2.3l. I think it is blowing hot air and running with more internal parasitic drag. All the new cam phasing, direct injection, and all of that just to get the same power as the LS9??
Makes you wonder what the mid cycle refresh is going to bring.
