By the Block number 2825409 I have a 1940 216cid engine. I never thought different but I wanted to verify. Are there any good recommendations for these engines other then on the end of a chain at the back of your boat? The owner of the car is avid about using this engine. I am not sure what I can or can't do with it. Everything I find about these engines it if you want to enjoy the car, it must be upgraded. Now I don't disagree but my goal is to try and use this engine.
