Try going to www.nastyz28.com as they have a decoding chart that should help. Go to the forum ,go down to the "Vin , Trim Tag , and Drive train Decoding "section . You should find your info there . Also try going to http://nastyz28.com/gm-chevy-codes/c...s-suffix-3.php ! Good luck !

If you feel you need more exact info, see if there is a suffix cods on the pad in front of the passenger side head. You can check that on NastyZ28 as well. There is also a date code on the back of the block near the top of the bellhousing flange. With Small block Chevy's you don't need the exact year of your engine when buying parts as the parts interchange for many years. The parts from the 350's from it's introduction in 1968 thru 1985 will pretty much all interchange.

If you are unsure of something you're looking at, post a question and someone will be able to help you. If it is an engine specific question, you may get a faster response posting it in the 'Engine and Drivetrain' section.
