The time has come to finally see how much power Zac's 9.3 Liter (572ci) Big Block Chevy motor is making. We hit the dyno room at Smeding performance to get a lesson in how to properly break in a new engine and get it tuned from proper drive-ability and maximum performance.

Catch up on the k5 build here:
