Hi All,

I have a 1953 3600, but it does not have the original 216ci engine. Rather, the engine is a 235ci. The most I've been able to determine is that the engine is a standard 235 model and was made on Feb. 6th, between 1957 and 1962. Apparently, from 1957 on forward, chevy 235ci engines stopped using serial numbers.

So, how do I determine the actual year of production for this engine? I have the following information from the engine block: Casting # = 3769716, Engine ID = F0206A, and two other strange things cast into the block and located below the Engine ID boss --> They are CON 4 and B52.

Can anybody shine some light on my confusion?

Thank you
