I know this is an old thread, but I thought I would say a few things about this project. It is not a stroker, but he did improve the rod angle by a whole bunch. I actually did a similiar thing with a lt 500 piston but only had to lift it .375 to make up for the different piston not the longer rod. The problem with this is the crankcase volume gets a lot bigger. But they stuffed the crank to improve the pumping of the crankcase. very interesting. sorry again for digging up an old thread.
