What do these numbers mean on my dads 440 engine block?

[THE CHARGER PUNK]

I was at our garage 2day and was looking for a vin number or some sort of number/tag to gve me an idea what car this 440 is from, i know that it was out of a 69 something, so from what i could see as i couldnt get underneath the car until i jack it up i nthe next week or 2 this is what i found beside the oil pan on the passenger side, does anyone know what this number means??? its weird tho our friend/mechanic/mopar fanatic(owns 70 r/t and 68 r/t and 70 fury cop car) wants our engine and would gladly build us one the same as the one we have which gave us the idea that their might be soem significance 2 our engine, im going to look again when we jack up the front end,so is there any significance to these numbers?-MATT

That is simply the casting # of a 440 and the date it was built: Aug of 1969.  The VIN is stamped along the bottom edge of the block, just above the oil pan on the pass. side, about 1/3 of the way from the front.  They are stamped fairly small and it is probably dirty, so clean it first.  Since it is a 69, it should have the entire VIN # of the orig. application stamped there.

Actually a 8/69 casting would be for a 1970 model car which means it won't have the entire VIN. The plant code MAY help determine what it came from.

Check the pad in front on the driver's side too for an assembly date and and an HP stamping. It could be your block is more date correct for his 70 car. Just ask him why he's interested.

I'm guessing he wants to switch your HP Stamped motor with a Non HP stamped motor. I'd find the vin #, Write it down & make sure they do not pull a switch a roo on you. lLook for the other #'s stamped on small pad on top of motor also. LEON.

We asked him but he is tight lipped as he is an italian

with tha cast date it could possibly be an early 6-pack motor....does it still have the balancer on it? 

From www.440source.com.....

Shown above is damper #3512017, commonly known as a "six-pack" damper. This damper can be easily identified by a small .210" thousandths thick elliptical weight attached to the center hub. This version was used in '70 and '71 and has the offset pulley bolt pattern. Be careful not to confuse it with 3614372, which was used only in '72 and looks similar except for having a symmetrical pulley bolt pattern. The weight on the 3614372 may be slightly thicker at .255", but we have not been able to verify this.
Even though these dampers have an elliptical weight, they were never used with any cast cranks. These dampers were used with steel cranks and "six pack" (2951908 casting #) rods. The extra weight is to offset the added weight of the extra metal in the rods and pistons. Another important fact is that even though six pack rods continued to be used up until 1975 in HP and truck 440's with steel cranks, they did NOT use this damper. As you can see from the chart above, any 73-75 steel crank 440 (with either six pack or standard rods) would have come with the 3614371 damper. We have found this to be absolutely true.

First, there is nothing special about your engine block from a strength/durability/desirability standpoint. But if I was to speculate on why your friend wants it, I would have to think that he plans on making his 70 R/T a numbers matching car, and perhaps your block is a warrantee unit without a VIN/sequence number stamped into the ID pad, or else he believes that a correctly date codded block would somehow add value to his car.

I could be way off here, but those are the only reasons that come to mind for his interest as it's no different from any other 440 otherwise.

I know I get dissapointed every time I see a non HP stamped motor in a Mopar. First thing I think of then is some lame 280 horse station wagon motor or big boat C-body motor bought for $200 from local Junkyard. Just not the same as a 375 horse HP stamped motor. LEON.

Ya, bummer, we can't all have a hp 440, but a built 440 is still a bad motor, and if you have 375 or more horsepower in it, well, ?   If you don't have an original hp stamp, what are you gonna do?   

[hemi-hampton]

If you have a R/T car but dont have a HP Stamped Motor in it I say find yourself one. This is easy to do. The only Differance when you do find them is the Price compared to the lame non HP stamped motor. So the real Question is am I a Tightwad or Do I go for the Good Stuff for more Money, Thats the Question. LATER.

hp-hampton, ya, an R/T car would be a lot cooler with an hp motor, was thinking about going with the R/T clone plan, emblems and stripe mostly, but didn't think about not having the hp stamp, dang   mostly figured, well, it has a 440, could be an R/T, anyone that knows would know anyways I guess
