It is a great engine in its size class. There are even p-pump versions. Being utility tractor motors you don't see a lot of them in pullers but they could easily be built into the 1000+hp range on re-worked stock parts.

I am pretty certain you could not get that much bore in it. I think 4.375 would be tight. You have to remember that engine started as a 329.

Full Throttle Deere? I believe it was a 6.7 (new style. 404) punched up to 504. Maybe pushed too hard or something, never did see it run up to expectations more than once.
