I tore down the top end of my 01 Blaster. I believe it has a stroker kit, but need help to identify. The connecting rod is kind of a brass color and the case and the bottom of the rod have clearly been shaved down a little. The numbers on the rod are 43G. I measured the jug and it appears to be stock bore. Any info you can give me on those #'s on the rod would be great.
