Can anyone tell me some specs on this engine? I am assuming it's a 72 engine, but I don't know if they had 6pak rods or forged steel crank. It does have the small balancer on the front, but did it come that from the factory? I'm not sure when they started using cast cranks.

Not sure the difference between the 6 pack dampeners & regular steel crank dampeners but I'd say likely a PO had swapped in a good steel crank 440. Good score!. Here's a BTT & others may clarify further. EDIT this jogged my memory & I had a 73 fury cop car that had a six pack rods 440 & it was orange & I think all 70-73 orange 440's had six pack rods. If yours is OE turquoise then very likely you have a regular steel crank 440 Last edited by RapidRobert; 02/01/13 12:10 PM. live every 24 hour block of time like it's your last day on earth

Casting dates don't tell you what MODEL year the engine would have been originally assembled as since the MODEL year build started in August of the prior year. and an engine would have been cast at least a few weeks before the actual assembling of an engine. J is 73 , it could be either a forged crank or a cast crank. Look at the dampner . also if the engine has been rebuilt it doesn't really matter what the casting date is or what model year the engine is .

The casting date ends that speculation(of the block)... After 40+ years, we've seen all kinds of things stamped on the pad... A 'small' dampener would indicate a steel crank... A tear down ends ALL speculation...
