Yeah, it's looking very impressive. Also FYI, the rwhp number I showed is on the low side of what I've been reading for an LS7. I've read it to be as high as 480. Where it ends up on the Z/28 we'll have to wait and see.
For grins, 3,700 lbs. 480 rwhp = 11.5 1/4. With numbers like that and what we already know about its handling 1.05 G this thing is gonna be crazy!
