Brand new, never even out of the box, literally delivered to me this week. 4.030" bore, 4.00" stroke, for 6.125" rods. -1.8cc valve reliefs, teflon coated skirts. Rings, spiralox, and pins all included. Got a hell of a deal yesterday on a 3.75" stroke crank that I've been looking for, so I can't use these.
