I tend to agree with you Lawman.
Consider the following stats, mods, cost to get there:
2013 ZL1 stock: 580 HP = around 490 RWHP dyno
2013 GT500 stock: 662 HP = around 601 RWHP dyno
2013 ZL1 HPE700 799 HP = around 671 RWHP dyno
I am
greatly annoyed that GM does not give the stock ZL1 around 650 HP
to make it more comparable to the Shelby GT500.
ZL1 owners are shelling out $20,000 - $30,000 extra dollars to Hennessey ADM, or Redline to boost their RWHP to 671, which is still only around
70 more RWHP than a bone stock Shelby GT500 Stang and it voids the
GM factory warranty !
I don't think it's worth spending all that extra money to get more RWHP
but apparently many ZL1 owners do ?
I like Hennessey vehicles, they do great work but it's expensive for the amount of time, modifications, money required to get 671 RWHP.
I'm just saying...
