1972 Oldsmobile Cutlass 455 Rocket engine Has "Tick Tock Tach"

Runs great, engine and transmission recently overhauled. Has rust and needs body work and paint. This beauty was fully restored in 1991 as a 442 tribute and is just waiting to be restored again. The engine was put in in 1991 and the odometer has 31,912 miles since it was restored.

Forgot to mention, the interior seats were replaced in 1991, they are not original. The 455 cubic inch Rocket Engine is from a 1972 Olds 442. The "Tick Tock Tach" is original, factory installed.

There is a G on the engine, so I am making a statement that it may be possible the engine is from a 1971 Olds. I always thought my Dad's 442 was a 72, but it may have been a 71. The engine came from his car when he restored this car.
