On this episode of HOT ROD Garage presented by Lincoln Tech, Lucky Costa's personal '66 Chevelle gets major upgrades to its 6.0L LS truck engine. Tony Angelo and Costa install a set of AFR heads and a Magnuson supercharger on this high-mileage, well-worn engine to really wake up the powerplant. Without any upgrades to the 100,000-plus-mile bottom end, the #66ChevHell puts down more than 500 whp!
