I disagree. A parts room crank would have been exactly the same part that was supplied to the engine assembler at the Trenton engine plant.....spin balanced at another part of the plant using a specific bobweight.
okay, if you say so it must be true. I've only bought a few cranks over the counter at a Plymouth dealership and none of them had balance holes in them.
So in the end what your saying is that a forged internal 383 crank would have been balanced exactly the same as a cast crank external balance 400 crank and it's a true bolt in affair and will be within Chryslers balance limits?
I respect your debate, but completely disagree based on my own experiences.
