New crankshaft?
Does anyone have an recommendations as to where to buy a good crank for a 3.9L magnum? I'd like to stay away from some random cheap crank off of Ebay as I'd like to be able to reuse it for future plans.
Edit:
On the subject of crankshafts, does anyone know if the magnum 3.9L's came stock with fully grooved main bearings? Took apart a motor that I bought off of market place and I was surprised to find fully grooved mains. Bearings and crank are both shot, which surprises me for supposedly having 118k miles.
