The HorsePower guys take a look back at some of their favorite engine builds over the past couple of years. Included will be the fine 409 build for a Muscle Car Impala, a fabled 440 Six-pack and 588 Big Block Extreme motor. And its' dyno payoff time for the $2,000 budget LS motor. Plus, heads-up Outlaw racing from a fast track in Alabama.
