There are two main identifiers on the blocks for Gen I Chevy motors. One of them I could almost read from your photo if my eyes were better. Just above the passenger side top water pump bolt head, the block is stamped with what is called the suffix number. It is a combination of numbers and letters that tells the production plant, date of manufacture and the application of the motor....

Also, I would STRONGLY suggest that you rid the motor of that rubber fuel line and replace it with a more substantial line BEFORE you have a fire.

And the motor needs more air filter element area so it can breathe properly, a 14" x 4" should be about right.
