I found a 69 Coronet with a 440 in it. On the id pad on the RB it has the following:
8 16 2 X
I know the first 2 numbers are dates, but I don't know what the 2 X stands for. Anyone know? I haven't crawled under the car to get more numbers.
I received an answer from a fellow on "just ask" and I think he was quite helpful, I'm just getting a second opinion.

The 2 means built on 2nd shift and the X means over size valve guides

And without the HP in front of the 2 it means it was a 350 h.p. engine that would have probably been installed in a "C" body. Look at the V.I.N. stamping and I bet it has a plant code from a "C" body plant.

350 horse 440 was an option in the 68 and 69 net 500.

Thanks for the replies guys.
Would I have a problem building up a "350" horse 440? What are the drawbacks to that engine. Would it have a steel crank built in 68-69?

Sorry, not true. The only 440 available in a 68 or 69 Coronet was the 440 Magnum as the standard engine for R/Ts. The largest engine available in 500s was the 383 4 barrel.
The 350h.p. 440 was a C body only engine.
These are pages from the 68 and 69 Dodge Dealer Data Books showing the engine availability for Coronets.

If it is a 1968-1969 440 it will be a steel crank 440.No problem building up a low HP 440 no draw backs really.

Only the cam, exhaust manifolds, and maybe (If I'm wrong somebody will correct me REAL quick) the valve springs make the difference between a 350 horse 4 bbl and the 375 horse HP. Yes, it should have a forged steel crank and not a cast crank. Build away!

That is correct. They used the same pistons/same compression the only thing different internally was the cam. The HP designation was just the factory's way of identifing the cam difference.

I didn't know that....but I guess that's why I'm here.

and the springs on the heads are not the same no damper on a 350 horse, the springs are lighter. On a 375 horse they're heavier have damper :tongueflap: and 402 oil pan wintage tray
