J 440=1973 model year 440
maltese cross and X=.010" under crankshaft
7   1   could be a build day and shift number, but I'm not sure
3698830-440-5 is a 1973-78 model year 440
11-22-72 is the casting date

As this is a '73 model year it still should have the forged steel crank. If it came from a manual transmission car or truck, the crank will be drilled for the pilot bushing as well. HP engines in those years also had what we call 6-pack rods. It might not even be stamped HP and still have the rods.

I agree, but to clarify a 73 would have a CAST crank, UNLESS manual trans, HP, or something special (as you mentioned).

You may be correct, 1973 was a transitional year for the 440s.

But, because there is no 'E' stamp with the 440 and because every 440 I have pulled from a 1973 passenger car has been a forged crank engine, I feel he has a good chance of it being a forged crank.

If the vibration damper is part #3577785 he has a cast crank, 3614371=forged non-HP, 3614372=forged w/HP.

it does have an E on the top pad  the damper is the thicker one   thanks

what could this be out of?

It could be from a B or C body. Check the VIN on the passengers side. The plant designation will help narrow it down.
