The LS7 is wrong ! The LS7 with 465 hp and 490 lb·ft

version of the 454, dubbed LS7 was also designed but never went to production. However, a handful of LS7 intake manifolds were produced and sold by a few Chevy dealers as performance parts. The LS7 was later offered as a crate engine from GM and advertised at 500 hp. I am a former Chevrolet dealer and Owned 2 of the 454 LS7's. One was in a 1970 SS Nova and the other a 1970 Chevelle SS. I now race an L88 427 in my 73 Z28. Out of all the Rat motors, the L88 and ZL1 427's are the Kings of Big Blocks. Love the game !

nice. almost the same as a c6.r :)

I'm partial to the Corvette over the Viper - it's better suited to everyday driving and handles much better.

i won't play a racing game that doesnt have a corvette in it...i love this car

505HP is a bit weak for a 7-liter engine, compared to comparable engines from European cars. The Z06 is a good car, but I'm not sure it's the "American dream car" anymore, now that the ZR1 is on the road. Just over a $100,000 for a car that's not only good on the road, but near god-like on the track and much, MUCH cheaper than any equivalent European supercar.
@St. Anne:

While the Viper SRT10 may be faster than the standard Z06, it's a hell of a lot harder to handle on the road and on the track.

Yes, the viper srt-10. And who's american dream car, surley not mine.
