Hello, New to this site and was hoping that I could get some feedback or guidance on what exactly I have. I recently purchased a new holland l785 that had a hole knocked in the side of the block. The motor is a Perkins diesel and after looking the serial number up on it it says the JG code is a 4.2032 engine. I was wondering what the difference was between the 4.203 and the 4.2032 are. I found a block relatively close but it's a 4.203 and doesn't have the 2 at the end. Any guidance is much appreciated thank you.
