Among the Pontiac GTO parts, the engine is considered exceptional. The 6.6L V8 engine can produce over 350 hp. The original Pontiac GTO came in either a hardtop or soft top convertible. The Pontiac GTO came with a choice of either an automatic or manual transmission. The special edition Pontiac GTO Judge used a 4BBL V8 engine with 455 cubic inches that produced 360 hp and 500 lbs of torque. With only 17 ever made in the world, each Pontiac GTO Judge is paired with an automatic transmission and a Hurst "T" handle shifter. The suspension was outfitted with a larger front anti-sway bar measuring 1-1/8" and a rear bar measuring 7/8". An interesting option offered is the Vacuum Operated Exhaust System. By pulling a dash mounted knob, engine vacuum would open baffles in the mufflers. This helps to relieve back pressure and produce more power. To simplify your online purchases, we offer a broad selection of Pontiac GTO parts include: brake pads, timing belts, radiators, oil filters, exhaust manifolds and more.
