Pulling out my dragstrip calculator....This thing is rated at 500 horses. You have about 4050 kerb with a 150 pound driver aboard. Looks to me like it's making pretty much every bit of 500 and maybe a bit more.
1. Most people will never be able to push either car (Z/28 or a Boss) to it's limits and won't be able to say which car is faster or handles better on the track.
2. A new Boss was roughly $45k in 2013. Add $30k in upgrades and the only view of the Z/28 will be in your rear view mirror.
I could never consider a camaro, gm cars just feel cheap to me! Besides with an all new mustang gt and gt 350 around the corner its a no brainer for me! mustang blood is pumping through my veins, a transfusion is out of the question!
