The Z06's are the S H I T. They hit 12's in the 1/4 even here at 4000 ft. They weigh just over 3000 lbs and are very well made. And for a naturally aspirated engine they respond very well to mods. There are a ton of 03 cobras here and a few Z06's and the Z06's absolutely own the 03 cobras at the track. Hell the regular C5 vette's are bad mofo's as well. Nothing in West Texas is stock
With just a cam and ported heads there is a Z06 here that dynoed 430RWHP and more than that in torque. Yeah the 03 cobra can also dyno high numbers but its a heavy car and the Z06 is surprisingly light.
Anyone that believes the 03 Cobra is a better car I ask you this. Have you ever been in a Z06, I have and they are Bad.
This is comparing a true sports car to a pony car so it really isnt a fair comparison.
But for me as much as I like Cobras I like Z06 Vettes better.
