1969 383 crankshafts: cast or all forged
Mopar1us.com claims 69-71 2 barrel 383's were cast. Its going to be a street build anyway, so its not the end of the world.
Are you sure 69 2 barrel would be cast?
I've got a 69 2 barrel and I'm counting on it being forged if I rebuild it.
The dampener seems to indicate it is forged. Mine has a small dampener which appears to me to be a forged dampener.
71 2 barrel being the exception to 383s with a cast crank.
