I posted the engine numbers a while back and learned that they were not so easy to decipher. At least one source tries to tell me I have a 216 from 1950, which just can't be. Here are the numbers, no misprints: HAA 133972
Here is a picture of the motor. new motor
The head number is 3701887
It worked fine after my valve adjustment. But I am surprised by the springy resistance in the rockers/pushrods. Those rockers do not rock free through the motion of the set valve lash/gap.
