340 engine decoding

I'd almost bet on it........And the possibility of a steel crank is better then 90% imo. I'm almost positive i've seen a 72' steel engines date coded after that. If i'm wrong then let the beating begin....lol.:violent1::violent1::violent1:.

From what I read the "car" build date was before april not the engine to have a forged crank.But I haven't done any first hand deep research,I was just looking around to see if my 72 cuda that was built in nov 71 had a forged or cast crank.And aren't late 72's actaully 73's as mine was built in nov.
