AMC 258 crankshaft from 84 CJ that had factory serpentine belt system. We were going to use this in a 4.0 stroker (to make a 4.5, 4.6, or 4.7) because it is from a serpentine belt engine originally. We aren't going to use it so its for sale. This crank is a core that needs to be reground - it sat for years in the engine and the spots you see in the pictures are corrosion from sitting with moisture in the bearings. We indicated it in a 258 block and it was straight as can be - no runout.
