engine number stamp on the block

[Dr John OConnor PhD]

number stamp on the block 5(U/0)3456U5- SECOND DIGIT IS U OR 0
ANY ONE KNOE WHAT THIS MEANS, PASENGER SIDE ABOVE FAR LEFT?

That is typically a Vin stamp. What year engine, what year car?
Last six digits are numbers, yours are just badly stamped.

Can you get a better photo?

Does the VIN on your dash end in 345605 ?

 

[Dr John OConnor PhD]

no idea of year of engine, car 1965 dart

 

[Dr John OConnor PhD]

No vin does not

You have 2 threads about it now, makes it tough.

No partial VINs for '65 as stated in the other thread, but a clear photo of that pad would still help ID the newer engine.

I found a vin tag in the ash tray not sure if it is even from my car

What is the date code cast into the block?

 

[Dr John OConnor PhD]

no idea where would it be?

 

[HemiSSDart]

It is cast into the block on the passenger side of the block. The engine size is cast into the block on the drivers side...

not on a slant six

It looks like a VIN number, meaning it's 1968 or later, if I recall I read they didn't start stamping them with VIN's until after 1968. And yes that is going to be on the rear of the passenger side.

My 66 doesn't have a VIN, it only has the year/displacement stamping info stamped on a pad facing up near cylinder 1 towards the front of the engine on the passenger side as well.

Welcome to the world of partially-informative replies.
The number you posted is the partial VIN. It's the last 8 digits of the original host vehicle's VIN. The first digit indicated the year, the second indicated the plant the vehicle was manufactured at and the last 6 was the production sequence. Having a decent eye for poorly stamped Mopar numbers, that one might start with 3B, which would be a '73 engine installed into a vehicle produced at Dodge main.

However, there are other things that nail down the date. Look down behind the ignition coil from the top with a bright light. There's a pad on the block facing upward that contains more info. Once you scrape it off, you'll see a string of characters that resemble H225R 3018 1644. Your's will not be exactly the same but that's the format.

H225R...The letter is the year code. H would be 1973, G 1972 and so forth. 225 is the displacement, R is for regular fuel. The two pairs of 4 digits afterward are, in order, the 10,000 day calendar assembly date and then engine number produced that day. You can enter the 4 digit date code into an online decoder. They "might" be reversed between the pairs of numbers. There are no dates cast into the block on a Slant, that's V8 only. The 4-digit numbers cast there are not date codes. Last, it looks like the engine is wearing original Chrysler blue, so that's '70 up. Good luck.
EDIT: I just noticed cylinder head. That's a '75 and later head at least, so who knows until you find all the numbers.

3B partial VIN, so it is from a 1973 model year car made at Hamtramck. Could be from an A or E-body.
