Has anyone ever built a 403 inch moline puller. Something to complete against a John deere 4010 4020. Class limits are 404 inches non turbo and weigh classes from 7000 to 9500 pounds. Just thinking out side the box. Use a m 670 as a base .
 
Jus theory thinkin...how about gb deisel.425 cu. Decube a cylinder to 404 .. Lots option to do 404cu.or how about 336,,make bigger?
 
The misguided Ohio plowboy is on the loose...watch out!! LOL
I built one. 4 cyl, 425 CID. But I pull 5500-7000 lbs 18.4 tires, 4-5 mph speed limit open rpm (I run 2100). Turbo/NA mixed classes. I like having something different and its competitive too. Heads are the limiting factor, you'll want G-1000 Vista heads, inline pump if its allowed or at least a built up Roosa Master. The biggest head available for a 4 cyl Roosa is a .390, good for about 200-250 cc's of fuel, which would probably be plenty for 403 cubes.
