I know it has a steel crank - what stock horse power would this engine have?

that's a 350HP motor , the 02502 doesn't look like a factory stamping , probably a number added by shop that rebuilt it .
How do you know it has a forged crank ?
The thickness of the balancer?
If it is HP why no HP stamp?
Ok you are ASSUMING it has a forged crank. I'm pretty sure there is a thread here somewhere where a member bought a 69 440 that was done by a mass rebuilder of sorts ... it has a CAST CRANK .
HP means HORSE POWER , that is NOT a 440 375 Horsepower engine block , what it is NOW is anyones guess. I assume you bought it as it sits ????
Why isn't there 5 replies with a picture of a car that has nothing to do with your question ?

no offense, but call it all you want, but until you pull the pan , your guessing.
You already have pretty substantial proof it's been opened up

It was a high performance motor when produced or it was not or you cannot tell from the stampings? That was my compound question. Oh ok -- it is 350 horse power engine... dah
Can you tell if it is a steel crank by the balancer?
You obviously have a VERY LIMITED Mopar background ?
The 1968 440 came in 2 flavors , the LOW PERFORMANCE 350HP version , which that engine started life as and why it does NOT have the HP stamp on the pad and the HIGH PERFORMANCE 375HP version , which that is NOT .
Can you tell what crank it has by looking at the balancer ? Technically NO , unless one were superman and had X-Ray vision. You will have to pull the pan to be sure , BUT if that was in one of your cars and ran ok with no funny cyclic vibrations then it would be safe to ASSuME that it has a forged crank .

No offense taken,
Did this engine come with a steel crank from factory?
thanks
No , if it still has it's original crank it has a FORGED STEEL crank and not a CAST steel crank.
Steel crank , your corvetteness is showing ...

Obviously, the reason for the thread professor.
Thank you for the precise info on 68 440's
So...drop the pan and forged crank will look different in what way? thanks

Isnt it safe to say that a C 440 will have a forged steel crank "unless" it has otherwise been switched out for a cast crank? I dont claim to be a genius, just asking.
When mamopar built it? yes.

68 440 forged crank. 440's did'nt start coming out with cast cranks till mid year 73.
While that could be true for production engines when new, thats it period. After that all bets are off until inspected. Block casting numbers and staming numbers dont mean $HIT. Face it these are 30 to 40 year old blocks. Someone has had their paws in most of them by now.

I am calling it a steel crank, as i called the Charger a survivor. Until, some other member enlightens me.
