This has been discussed on here before I think
Does a JD 414 use a hopped up 404 block or a sleeved down 466 block. This engine is out of a combine I think but it has a small rotary pump |

It uses neither. It is based off of the 329/359 series engine. Basically it’s a 359 with a longer stroke. It’s really a 300 series engine. Different animal altogether. |

So a guy is better off sleeving down a 466 or finding one from a newer tractor(7410 for example) |

You could put 4.3" pistons in a 404 or a 466 block and be 413.87 cui. And still put a 7.6L head on it. That way you can still use the readily available parts. You will want to use billet pistons and steel sleeves anyway. |

I think it depends upon you (green boy), your skills and resources. The 414 does not have a ready supply of performance parts you can order or pick up used. However, the head design of the 414 may work better if you want to go with a 5” stroke. If you want to be different and are able and willing, go for the 414. If you are not in a position to be a trailblazer go with the SB as bonestock described. |

Umm, 414, is a Dubuque small block. Same as the small modern ag 3 & 4 (219, 259) cylinders plus 6 cylinder 329, 359 & 414.
404, 466 & 8.1 Waterloo engines are not a small block. They are the middle motors, between the small block and the big block 531 / 619. I do not understand why people want to keep calling the mid series a small block. That is as bad as National Weather Service Watch / Warning, as there description of the 2 terms is exactly opposite of the dictionary definition. |

Based on popularity the 404/466/7.6/8.1 has, in the pulling world, always been referred to SBJD.
While I see your point, there are damn few Dubuque small blocks hitting the popular classes of pulling. Just the way it is. |
