I have read that 70 series gas heads will bolt to a 30 series gas block. So, can you do the same with the diesel heads? Is there an advantage to the 70 series heads? I am thinking that I can take an 830 block and bore it to accept 870 sleeves and basically have me a 870 out of an 830.
Can I go bigger than 4-5/8 and still farm with the tractor? What kind of stroke can be had out of a 830 block without spending a ton of money?

The intake/exhaust is on the opposite side from 30 to 70 series. Fuel pump and injectors on opposite sides, so custom fuel lines will be needed. There is a center head bolt in the 70 series that is not in the 30 series. Not sure if the pullers drill and tap another hole in the block or leave that bolt out. The direct injection heads give you another 15 to 20 hp and better starting. I've never done it but thought about it on a 1030/1070 setup. Good luck either way.

Okay,
I knew about the bolt hole thing. When gas heads are switched they just plug the hole. I would imagine it would work on the diesel also.
I wonder if the 830 and 870 use the same fuel pump or if they are different. I could see where a 336 830 with the direct injection could put out 100 horse. Hmm maybe I need to get to work. Thanks for the help
