Getting straight to why Sudden Death was so notorious, the main reason is because shortly after its initial completion in 1977, during which it was loaded a 500-plus-horsepower, 505-cubic-inch big-block Ford engine (a bored, stroked 460 with 429 Cobra Jet heads), Jack updated the powerplant with twin turbochargers, giving the Pony more than 1,300 horsepower. In a later restoration by Tom Tate, one of six people who have owned the car since Joe campaigned it (including Jack, who currently owns it), the turbos were removed and the big block received a new solid-roller cam and ported Blue Thunder cylinder heads. Naturally aspirated horsepower currently is in the 500-hp range again.
