You'd be better off with an M5R2 than that one. They put them in the F150's and can be had fairly reasonable. They aren't an NV45 or ZF but unless you intend on constantly putting over 300 lb-ft thru it every time you shift I bet it would work fine. I have one with 188,000 miles behind a 5.0 which was 185HP, 270 torque. They got a bad name because they have rubber plugs on the back of the shift rails that started leaking and if the owner didn't pay attention to what was happening the tranny burnt up due to lack of oil. Mine started leaking and I took care of it, no problems. That's the risk you take getting a used one, that it was run low on oil. Note, the R2 is the preferred choice over the R1. Trans. longevity is directly related to its torque capacity and how its used.
