One of the best parts about SEMA is getting to see the manufacturers build cars they might not otherwise. Take this G8 GXP Street Concept, for example. Sure, the 415-horsepower 6.2L V8 in the standard G8 GXP is plenty good enough, but why not stuff the new LSX454 crate engine from GM Performance Parts underneath the hood? The 7.4L V8 is good for a ZR1-matching 638 horsepower and 600 lb-ft torque, allowing this G8 to unashamedly call itself a true muscle car.
