Also the block casting date should be on the passenger side of block.

Hey John,Since the cover is off, and I assume you have the power steering off too, you should be able to see these identifying numbers. 1972 should have "H".
With all your messing around with this, I think you'll be better off biting the bullet and replacing the cover.
Thanks. I will look harder to find the number (passenger side too). May be a bit, but I'll post the result.
As far as replacing the cover, I agree. However I don't have the luxury of getting a new one right now. NO time. Need to get this thing going pronto.

Yes, I wouldn't want to have to r and r the cover after reinstalling it and all the associated parts.
Latest is there are several "reputable" machine shops nearby and I should be able to have the cover surfaced, welds cleaned up and all checked out. I will keep my fingers crossed. But, bottom line is not going to reinstall without having it serviced further first.

Hey Don,
thanks for the offer. We'll see how the repair goes in La Paz. If it's a total nightmare I may be hitting you up!

It's an idea!! Love that photo on your profile! So classic.
Maybe marine tex is the final frontier before replacing the whole thing. Let's see how they do in La Paz...

Hey Big John,Since the cover is off, and I assume you have the power steering off too, you should be able to see these identifying numbers. 1972 should have "H".

I finally got around to looking at the engine stamp and this is what I found:
"M318R 06 131947"
After revisiting your post here I am concerned that I'm missing a letter at the beginning... I can look again but after a fair amount of cleaning and flashlight work the only letter before the 318 was "M".
Does this make sense? The primary information I am looking for, of course, is the year of manufacture. Figures.
You can also look at the engine casting date on the drivers side of the block. There will be a casting number just below the freeze plugs #2536030 from '67-'75. (318 engine) Just below the casting number is a casting date which give the month, day and year the block was cast. Model year production usually ended in about June and then the plants were retooled for the new model year. Most engines produced early in the production cycle will show, for example, a Sept '70 production date for a '71 model car. Engine casting date should always be before the build date of the car.

Here is an example of a mopar block and date casting number from a big block, the same pattern was used on most mopar engines.

Hi Dave, thanks for the reply. I can see on your engine clear as day that it was built in '68. Any idea on the number I found on my engine (behind the power steering pump)-M318R 06 131947??
it's a little hard for me to tell exactly where your stamp is located- I guess I'll start by looking for the driver's side freeze plugs, below the head. Might be hard to see with the exhaust still mounted, I'll look.

Those numbers don'y make a lot of sense to me.
The numbers after 318R should be the 10,000 day calendar. Chrysler's 10,000-Day Calendar
Plug "0613" in and that's 1963. So, I guess I would question if that is really a "0".
M is for Mound Road assembly plant. 318. Those seem ok.
I think you have to look at the casting numbers like Dave is saying.

That's not just a big block, that's a 426 hemi! Small block casting dates (at least the early ones) are located on right front near motor mount, here's a 273 for example. It will be hard to see in car. BTW, still think you should bite the bullet & just get a good replacement cover. Do realize shipping costs to MX can be outrageous.
Here
is a 318, casting number and date are visible on the driver side of the engine.

Dave and John, here are the numbers I pulled off the block: 1283 2536030-G18-2BN.
That last capital G maybe being a 6. It was hard to tell for sure.
I will try to post a photo of the stamp soon-I’m a flip phone guy and only had my phone on me at the time to take the photo. Gotta transfer to my wife’s phone and then I’ll post it
