I recently found the crank shaft diagram and it shows 2 different crank shafts for 327 which is a better choice for a new engine my current rebuild project has a steel crank I'm going to check for large or small journals. This engine came with 2 sets of camel hump heads one set is 194 valves the other 202 what is the difference year wise my car is 1962. I am a mopar guy and all this is new to me. Thanks Colin
