I have put these and the 6 cylinder versions in Majors.
Even being a 4 cyl they are ignorant to fit. the oil pan is completely wrong being made of aluminum, , there is no place for the wishbone on the front axle, so that has to be converted some how, either under or out front. I did mine out front.
The top of the block lines up to the tractor but the bottom from oil pan down is a different shape, the bolts don't line up and it needs major re working to make it work and strong.
You can"t fit the tractor pan as the blocks are totally different so that's just a pain. when I did mine i had to cut and tig weld the oil pan. altering the front so the steering track bar fitted in the standard place, without moving the axle forward and lengthening the hood, drag arm and frame.
The front motor mounts need work/ fabricating, and chances are the cooling hose on the bottom of the rads the wrong side. That needs a cross over tube making or the rad altering all the ones i've been involved with needed work.
To be honest when mine was running it had loads of power and i spent a lot of time doing it as right as i could.
At the end of the day it looked and worked good.
But it destroys the value of the tractor. There was one advertised in Ontario $1500 last year, don't know if it sold or not.
It kinda makes me want to smack the guys up the side of the head, that put these motors on flea bay, saying direct bolt in replacement for majors.
It never has been and never will be, trust me been there done this more than once!.
If you decide to do it be prepared for a lot of work not just 2 afternoons,
