2 Bolt main..What the heck you're waiting for ? If I've ever lay my hands on one.... The 1968 Ford Thunderbird has a spark-ignition, four-stroke V-8, valve-in-head engine with a displacement of 389.09 cubic inches (6.4 liter). The 1968 Thunder Jet has gross power of 315 horsepower at 4,600 revolutions per minute (rpm), a gross torque of 480 foot-pounds at 2,800 rpm and reaches a top speed of 135 mph. The Thunderbird 429 has a carburetor fuel system, dual exhaust and a centrifugal water pump cooling system. Additionally, this vehicle has a compression ratio of 10.5-to-1, two valves per cylinder and the option of a three-gear automatic transmission, or a four-gear manual.
