In this installment, the 1966 GTO's L92 V8 finally comes to life! Once we had our MagnaFlow exhaust system connected to the polished ceramic Hooker LS1 A-Body swap headers, we topped off the fluids with Royal Purple Synthetic Engine Oil, MAX ATF Transmission fluid, and Purple Ice radiator additive. We didn't want to risk anything, and the protection of Royal Purple against heat, friction, wear, and moisture gave us peace of mind. Plus the reduced friction frees up power. We run Royal Purple in every car we build and drive. But the real challenge was finding the little electrical gremlin that kept the MAST -powered ignition system from firing. It was our fault, and when we fixed it, it came to life in the push of a start button. The GTO runs and sounds fantastic!
