John Deere engine block question July 13, 2013 01:59PM
I'm sure this is a really stupid question, But I'm trying to up my pulling IQ. Which JD engines are big blocks and which are small blocks? I'm assuming a 404 is a small but how about a 466? Can anybody help me out here?

404, 466, 7.6, & 8.1 are considered small blocks. The smaller 303/329/359/414 series are sometimes referred to as Waterloo engines but probably don't have a standard name.

303, 329, 359, & 414 are called Dubuque engines........where they were built.
