I am very grateful for the research you have done.
I believe that 3731548 is the casting number because I can see 731548 now
that I have cleaned it better.
It does have the cannister type oil filter. It is a 2 barrell.
You can bet that I will save this message for future reference when I have
the valve covers off.
I am pleased that this motor has a forged crankshaft and the heavy duty
pistons. It should last a long time.
Where would the crankshaft number be located? Any idea of the compression
ratio? If I am being a nuisance, please let me know... It is exciting to
find someone with the knowledge you have about this engine.
