Chevrolet Performance LS3 crate motor

You already know we’ve chosen the powerful and compact LS3 for this build, but which LS3? We went right to the top and got the LS376/525 crate engine. It’s the most powerful production-based crate engine in the Chevrolet Performance portfolio: 6.2 liters, 525 horsepower at 6,300 rpm and 489 ft.-lbs. of torque at 4,400 rpm.
