Bob,
Here is the calculation for engine displacement:
pi/4 x (bore x bore) x stroke x no. of cylinders divided by 1000
You first have to convert your measurements from inches to centimeters.
I came up with 2232 CC with the numbers you provided. Have you checked
the top of the pistons for the over size number stamp on them. You should
also be using a inside micrometer to accurately measure the bore.
The stamped steal pans do come with a baffle in them.
Hmmmm!! I wonder who noticed the bad cam and the welded upper chain guide
:-)
