Has anyone actually done this to the S65? I was looking at the Dinan and RD stroker versions of the S65 for this reason. They have much better rods (and I assume, rod bearings) as well as lower compression rates for FI applications. I would be willing to bet their clearances are better as well, since the engines are blueprinted and bored. I don't think anyone has done an FI stroker build, but I would love to see it tried.
