That's the nature of the Parts Master. Sometimes what it doesn't say is as important as what it does. Based on the sequential assignment of catalog/casting numbers you've got the second series design - which jibes with a '59 261. If you're looking at replacement parts with the listed casting numbers above - they won't work with your 2nd series engine.
Ok, I'm a little confused. My engine block casting number is 3759365 and the part number on my cracked front end cap is 3837210. Also on the passenger side of the engine is what looks like a stamped serial number of N368472CAL Where can I find out more info on this engine? Thank you.
