The beautiful Black 1979 Pontiac Trans Am is a combination of beautiful styling, superb handling, and strong Pontiac V-8 performance that makes It highly coveted by collectors and performance traditionalists alike. The '79 (5th digit of the Vin # is Z} code-PWH T/A 6.6 was assembled using a No. XX481988 400 block, which featured a 4.12-inch bore. Its bottom end was filled with a 3.75-inch stroke cast-iron crankshaft, while cast-aluminum pistons on cast-iron connecting rods filled the cylinders. A 60-psi oil pump dispersed lubricant and resided within a baffled six-quart oil pan. A Special 800-cfm Rochester Quadrajet carburetor on a cast-iron four-barrel intake manifold feeds a custom set of headers routing spent gasses into a ''Y'' pipe and dual turbo mufflers before it exits out the Rear. The net result of the effort is a rating of 250 horsepower at 4,000 rpm and 320 lb/ft of torque at 2,800 rpm. engine looks as it did when it was built and sits in a very clean and detailed engine compartment with the correct shaker hood scoop, chrome valve covers, and power steering and power disc brakes. Backing every T/A 6.6 engine throughout the '79 model year was an 11-inch clutch disc and pressure-plate assembly, and a Borg-Warner Super T10 four-speed manual transmission with a First-gear ratio of 2.43:1. Because the WS6 Suspension Package was required with the W72 Performance Package that year, all Firebirds equipped with the T/A 6.6 received a 10-bolt rear axle filled with a 3.23:1 ratio gear set, and new-for-the-year J65 rear disc brakes on either end. Our 1979 TA great cloth Interior has bucket seats, center console housing the 4-speed shifter, black simulated leather-wrapped Formula steering wheel, and an engine-turned instrument panel inlay, the standard Rally Gauge cluster which included both a clock and tachometer, power windows, and air conditioning.
