ok lets do some math
Typically, a FWD car sees 13% drivetrain loss, in a RWD its more, so lets be extra generous and say 15%.
HORSEPOWER=TAKEN FROM MOTOR TREND
now STOCK ZO6 makes 405bhp.
406*.15=60
405-60=345whp
Stock 05 VIPER makes 505bhp.
505*.15=76
505-76=429whp
Advantage Viper=+84whp
Curb Weights=TAKEN FROM MOTOR TREND
ZO6 Corvette=3130lbs
Dodge Viper=3280 lb
Advantage Vette=150lbs
not enough weight IMO to make up a 84whp difference. i didnt do numbers on TQ.
If i had to bet money, it would be on the viper. Now, it seems the viper cant drive, but, a kill is a kill if he was serious about racing. IF he cant drive thats his problem, not marshalls
