I'm thinking of doing a engine switch in a 300 hp articulated ag tractor I have. Current OEM engine is blown. A friend installed an 855 Cummins small cam in an ag tractor he has. Just wondering about the functional difference between a big cam and small cam 855. Which would be better? I'm engine knowledge challenged just trying to educate myself a bit. Also he suggested a Cat 3306 using a Steiger bellhousing. Which would be a better. Love to hear views from experience. Ag tractor operation around 2000 rpms constant rather than up and down like a truck seems to also be a factor. Any guidance appreciated

Looking for a road worthy Pete 372. The darth vader one. Anyone know of one for sale.

Looking for an Autocar tractor preferably with sleeper. Prefer tandem drives. Needs to be roadable but nothing too fancy. The heavier spec the better. Something I can use (max 2000 miles/yr) but fix up a bit too.
