Is the distributer in the fount of the motor or in the rear?
Ok trying to narrow it down
Oil fill tube in the fount of the motor?
If so there is a set of numbers stamped on it
Can you pass those to me please
Let me know if this helps you!
The number stamped on the oil filler tube is the engine unit code. The first number indicates the year the engine was assembled and the remaining numbers refer to the sequence build code and size,
1972- year of engine
562- is the cast line code
on the olds engine 0 to 4 is a small block
5 to 9 is a big block
If the fill tube is the correct tube for the engine you have a 1972 455 engine
Let me know if i can help more!
