Crank-Balancer-Flexplate?
I need direction with a 340 I'm about to build. It was previously a marine engine that I'm converting rotation to use in an A-Body automatic. The crank had a flywheel and the balancer that was NOT stamped "Use with 340 cast crank only".
My first question is whether the crank is cast or forged? Although the block is a 73 I'm curious if Chrysler used forged cranks in their marine apllications. It looks very simular to a 69 340 crank I have.
Second, Will I need to replace the original balancer and match a flex plate to use with an automatic?
Thank you A-Body memebers.
