Originally purchased in 1994 by his son-in-law as a drag-racing project, Bill Lorenzen took ownership of this '67 GTO in 1996 and quickly turned it into a consistent 12-second performer. Since retiring from his full time job in 2001, he has transformed it into a monster that's capable of running in the low 9s. Launching at 3,800 rpm and shifting near 7,000 rpm, the 2,680-pound GTO has produced a quarter-mile best of 9.21 at 142 mph. A Biondo Mega 85 delay box is employed to enhance consistency, while peak power occurs with 36 degrees of total spark lead. According to builder and crew chief Randy Moore, trap-speed calculations indicate that the mill is churning out roughly 715 hp at the crankshaft.
