So I found an old Mopar block buried in my yard.
Problem is I’ve been having trouble identifying it. Casting number leads me to thinking it’s a 383 but the casting date reads 72. Last year for 383 was 71. Hmmm
After multiple attempts to get something off the data stamp I gave up. Pencil rubbing didn’t help at all but a few numbers were found but nothing I could piece together. (See adventures in quarantine part 2) I really think it’s been ground off, more on that later. I had wanted to measure the bore, so I ordered a battery for my old digital calipers. Well I either ordered the wrong battery or my 20 year old calipers be broken. Oh well plan 2.
While not being accurate still better than the tape measure. 4.1 or abouts. Still not really helpful but kinda rules out a 400.
Off to the forums!
According to this. I think this confirms it’s a 383 block since my block doesn’t have the strengthening rib along the freeze plugs.
So I think I can confidently say it’s a 383 block. What it is actually is another matter. A 383 mopar bore should be 4.25. I may be off on my measurements but 150 thou. seems like alot. Pretty close to a 361 but the casting date of 72 doesn’t seem right but Chrysler at the time probably didn’t waste much. A guy at allpar said it might be a 361 truck block but information was hard to find. So I probably won’t know until I get the crank out.
Hmmm if can get it out. That might be awhile. Anyways the local rumor in the neighborhood is that back in the 60s and 70s the people that owned my property ran a little chop shop. I’ve pulled car parts out of the woods before . One of my first Oppo posts was me pulling pieces of a old Ford van out of there. So I decided to go a little deeper in the woods to see what I could find.
Wow several cars rusted so bad it’s hard to tell what they were. The yellow pieces are some of the van. Tons of trim and even more rust oh and a battery nice.
I pulled some of the more interesting pieces out. The door sill says Plymouth and was found by the burgundy tail light anyone know what it is? The dually fender is a Chevy but the rest?
Weird back window too. My woods have always been a good bottle mine but damn this is too much.
