I ran them in my Windsor. Alot of people run them and they work fine. However, have them installed by a competent machine shop that has done them before. One thing you need to be aware of is the thrust bearing width is different than most aftermarket 2.75" journal cranks. Most of them are a Cleveland width(including the SVO stuff) while the bearing spacers (at least the ones I know of) require a windsor thrust width, which is a little wider than the Clevelands. To make an existing crank fit, you'll probably have to have the thrust width of the crank widened (I forget how much, but it's something on the order of .015")
