Big Diesel

[Shawn W]

Has anybody ever succesfully build a large cubic inch diesel.
Im thinking close to 700 cubes in a GVI to play in the 10000 and 12000 NA classes against V8 massey's, Oliver's, and big block Deere's
the class is limited to 700 cubes.
Or would you have to go with a G-1350 or something you could put a 585 and build. Just never seen anything like that in the class. I'm sure i couldnt afford to build anyhting like but would like to know if it's possible and still have a engine you could trust to last and not a gernade waiting to happen.
Thanks
Shawn

I have heard of some guys using the 585's and boring them out to get the extra cubes and then either having new heads made or having the 585 heads re-tooled to use cummins injectors. I think most of those N/A classes have a 3000 rpm limit. If you can get the pump and injection system to give you enough fuel, with those rpm'
s and the extra cubes I would think you could be very competitive. I think 225-250 horsepower would be competitive in that class??? Biggest issue with 585 is heat.

I run a GBD with 668 cubes, in 7500 lb class w/ 20.8x38 cut tires, in 3rd gear @ 2500 rpms. It's a tough tractor to beat

An HD800 crankshaft drops in a 585 diesel. I was going to try it in a GBD, but sounded expensive. After picking up a G1355, it still interests me.

Shawn, I have often thought the same thing. But there is already 1 runnning with a 6cyl moline diesel in the class. It has White sheetmetal on it. I know the association you are looking at, and I would love to see a propane engine in there with all other rules being the same. I would really like to see how a good propane stacks up against the v-8 diesels, but unfortunately I don't think that will ever happen. I think they like there diesel only rule, even though a 651-700 inch propane motor would be relatively cheap and reliable to build. I frankly just don't know how it would stack up. Its a very good class, I would like to see what kind of ground speed they could achieve if they reduced the weight of the class a little. Brock
