Mike Szwed shared a few photos of his Farmall M Conversion to 2-71 power, with modifications similar to my own. Nice looking Tractor! Also, shared are pictures of a 706 conversion to a 4-53 Detroit which is still in process. I like the dual air cleaners to keep inlet restriction low. Looks neat as well! I started with this approach on my 400 but changed to a single paper element.
