Post the numbers here there is a host of experts that will decode for you. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | Yes, there are physical differences between early and late 235 engines. And there are a few differences between car and truck engines.
However, the advice above is how you can find out what year engine you have.
