A friend gave me what is essentially a complete engine several years ago. I have had it in dry storage for all the time that I've had it. The engine is disassembled (head and manifold, valve cover and oil pan off, crank still in the engine). Without having to move tons of stuff to get to the side of the block to get numbers, I have found the numbers on the cylinder head and the manifold. I am trying to find out if it is, as I think it is, a 216. The numbers on the cylinder head are outside of the valve cover seat---2194819 with an X underneath. The manifold carries the number2190407 with a P above it. The motor mount is still mounted on the front, which leads me to think 216. Any info that you can provide will be appreciated.
