"A big part of the Newtonian bitch slap is the 556-hp, supercharged 6.2-liter V-8. Dubbed LSA, the Caddy engine could be considered a slightly detuned version of the ZR1’s 638-hp LS9, but its titanium-free valvetrain and connecting rods and its conventional wet-sump oil system actually make it more akin to a supercharged version of the standard Corvette 6.2-liter."
