M W add power pistons.

Anyone have any of the factory info on how much HP these were to add on the various JD models ?
 
Look up "jd2cylservice.com" Duane Larsons site. There is a section in there under "aftermarket equipment" and has all the different providers through the years,manifolds/heads/power blocks and a section on M&W add power pistons with an original chart from M&W. Example would be late "B", 28.5 stock and 33.0 w/add powers.
 
here you go.....

I am assuming because they aren't going to gain anything in a tractor that already has a 16:1 or higher comp ratio. They are at a point of diminishing/no returns. Maybe they had a better dome for more fuel mileage?
 
Main reason is they were all ready at 41/4 bore but the new style power seal rings did help starting and maybe a little on fuel use
