hemi id help

I did not mean that Marines were UNstamped........
It should have had an 'M' stamp, and a close inspection likely would have revealed 4 small holes or 4 small spots where the rivets were sheared off.

.

 

Ahhh... Yes. I missed capital 'M' and plural.

Never even thought to look for the tag holes. Oh well...

 

Weird. No stamping on my industrial block at all. But it has the tag...

 

The 59 354 truck motor I recently tore down had the numbers stamped under the drivers side head. Nothing on the top rail.

 

Post this on the proper hemi tech thread so it doesn't get lost.

 

Gonna' link this sucker up to the ID thread... This whole THREAD is too NOT to link! Great info here!

 

I would guess/hope that were over-the-counter service replacement blocks. BUT, if I have learned nothing else while messing with MotherMopar during the last 35 years, it is "Never say Never".....

.

 

I rechecked the block, specifically that location. It has numbers stamped there, "8541". But that's it. And those don't match anything on the industrial tag.

Would a replacement block have an industrial tag? The numbers on the tag seem to match up with the casting numbers, and the drive rivets on the tag look right. I suppose the replacement blocks would still have tags if they were for an industrial...

 

My block is stamped VT552 Nothing else. The stamping is a bit larger than that usually used on the upper rail. As Gary said, you just never know. 60 years after the fact, and we are still "discovering" things.

 

If it was a service replacement block/assembly, I want to believe that a conscientious mechanic would have re-installed the old tag on the new block.
...yeah, I know...I have too much faith in people...

.

 

I checked my books and internet sources and couldnt find that number either, perhaps you have an industrial version. Not a lot of info. On those engines. They did put the hemi's in everything from generators to farming combines. Sorry i couldnt help on this one, usually i can answer these hemi number questions. Ill have to check back and see if it gets a right answer.

 

I just bought a 1955 331 industrial engine. Was on propane on an irrigation well. It has no letters on the engine serial at the front of the valley just numbers. And no riveted tag. Plus the valve covers are smooth. No chrysler firepower on them, no industrial on them, nothing just smooth with plug covers.

the block casting is 1619829-6
serial 348 3649
date on block 5-16-8? Did they make 331's in 58?

 

Casting # is for a '56 354 car, but would be a truck 354 block 57-9. See if there might be a use code on front of block on the driver's side of the W/P, below the head.

 

I know this thread is dead , but I to have found a Hemi with the numbers stamped upside down . My number also starts with an N and ends with CAL . the number is as fallows N330302 CAL . Any help would be greatly appreciated.

 

Bump

 

Should I start my own thread ? Just wondering if anyone found anything about these odd motor numbers


Sent from the frozen North

 

I'll guess that it's a warranty engine that came w/o a use code & a machine shop or owner stamped that on there. Some truck hemis have been reported with use codes stamped on the front of the block below the driver's side head, might check to see if anything is there.

 

Hi,..haven't been on in a few years. Anyhoo, can an engine serial number (392 Hemi) be decoded in such a way that a person can find out the exact model car it was installed in at the assembly plant?? I have a '57 392 that came out of either a New Yorker or a 300C,but I don't know which.Sure would appreciate it if someone was able to clue me in. The Engine # is: 3NE57-1787.

 

New Yorker, according to Tex Smith's book.

 

If it is a 392 lay your thumb on the water outlet on the front of the head if it fits between the water outlet and the valve cover it's a 392 if not it's a low deck.

 

Th

Thanks...can you give me the title of the book so I can go on eBay and order it?

 

When selling a hemi they are all 392S. Buyer beware

 

It's out of a 300, not a NYer.

 

Tex Smith's Complete Chrysler hemi engine manual by Ron Ceridono. You could try hot Heads, E Bay or the publisher Hot Rod Library , don't know if it's still available,

 

Most everything in the old book is now on the web. Perhaps not all in one place but...
Also, keep in mind that there are multiple 'errors/mis-prints' and such in the book. The contributors to the book were not given a chance to review the work before publishing.
As George says, a 3NE57 is a 1957 Chrysler 300 block.

When I had these type questions, before I knew of this site, I always emailed Bob at Hot Heads and he always emailed my back with answers. Looks like you have gotten outstanding advise though.

 

Sorry, I rechecked. 3NE57 is listed as Chrysler 300, as George said!

 

Bingo on that, but in this case he has the use code.
