Hello I was recently on a web page called thedieslepage its all g.m diesel stuff wich I love and what i saw on there blew me away it was a 6.2L diesel in a massey ferison tractor but far from stock this is a pullng tractor with the shaved tires this 6.2L diesel reves 5500 rpms it screams there is a 2 min video of it pulling the engine must have like 800 hp but im not sure full pulls where nothing for the 6.2L diesel it has 2 pumps on the engine to get correct fuel to the engine it also runs a super charger not a turbo. I only wish i had this engine in my old 82 chevy truck. if i did I would be at the diesel drags and kicking some ***. I love to see a engine that is a under dog to other diesels like the powerstroke and cummins have the ability to keep up with the big dogs and kick some ***. if you wanna see the tractor go to www.thedieselpage.com
