Did 72 440s come with cast cranks?. I know they went to cast cranks in 73 but wasn’t sure about 72s.

Our 72 440 is steel. We have a 73 440hp...also steel.

My 72 has a forged steel crank. Go to the 440 Source web page and check out the "Everything you ever wanted to know about the 440 engine".

My engine builder, RPM Racing Engines, said of my crank, " Man! THAT is a beautiful crank, i seldom see one that perfect."

Of course there’s the “rule” that certain years started something, but there’s also left over parts that get thrown in, so who knows!

All 440’s I’ve seen have forged crankshafts thru 1973. The direct connection engine manual had a lot of wrong information in it. Motor home blocks, thin wall ‘76-‘78... other stuff I can’t remember. I passed on many late blocks because of that.

The 440 Source article calls out those mistakes and myths and straightens it all out. Should be made a sticky here......
440 Source.com Everything you've ever wanted to know about blocks and more....
Lead in on the article:
Blocks are one of the most misunderstood aspects of building a big block Mopar engine. Never has there been more misinformation, propaganda and rumors floating around. In the many years we have been involved with the big block Mopar engine, we have seen and owned many many hundreds of used core engines. We have used this opportunity to try and keep records as much as possible as to different advantages and disadvantages that various blocks offer. All the facts listed below are the result of our independently testing, measuring, sonic checking or otherwise gathering information directly from original sources: either the blocks themselves or the original factory drawings (blueprints) that Chrysler used to manufacture the blocks. This eliminates all chance of secondhand information, rumors, marketing or sales talk, etc. Hopefully this page will help hobbyists, restoration experts, and racers decide which choice of block is best for them.

However.....even THEY get it wrong sometimes. My block is out of a 72 Charger. It's build date is 3/3/72 and the casting number is 3698830 which 440 Source says is a 1973 casting number. Can't be true, my block is clearly stamped 72 and came out of a 72 Charger, numbers matching original motor. lol.
