need help with engine details what does this mean

[remta1]

have been trying to find details on my 68 charger where do i find the partial vin number on my engine ?..on the passenger side engine block numbers read 246813012 ( and below it LL )
on the rear of the drivers side at the back of the motor where it bolts to the transmission it reads pt383r 2398166 and the trans pan has the number 402 stamped on it . on the side of the block on the drivers side i have 9 11 67 ( motor build date ? )

my vin ends with 297389 and my build sheet also says 297389 none of the numbers correspond  with the vin tag and the car was origionally a 383 2barrell and ...maybe a matching numbers car
"
NOW THE REAL STUPID QUESTION ....... is there anywhere else i should be looking to confirm matching numbers or is  what i see is what i get and it aint a matching numbers car ... sometimes there are casting numbers in some stupid places  AND I CANT SEEM TO DOWNLOAD ANY PICS

On '68's the fender tag serial number matches  the radiator support stamping and trunk lip stamping. The VIN number should match the transmission stamping number. At least it did with my 4-speed transmission http://www.dodgecharger.com/forum/index.php/topic,38316.0.html. Further looking matched a serial number on the transmission with the engine (located by the oil pressure sender at the upper rear of the engine) to prove it was all original. On automatic transmission Chargers it should theoretically be the same.

on the rear of the drivers side at the back of the motor where it bolts to the transmission it reads pt383r 2398166

PT-Plant Trenton (Built at the Trenton, MI engine plant)
383= Displacement
R- Regular fuel
2398= Build date February 20, 1968
166= The 166th built that day

the trans pan has the number 402 stamped on it .

Sure that's not the engine oil pan?

on the side of the block on the drivers side i have 9 11 67 ( motor build date ? )

Thats the date the block casting was poured, build date is above.

Also, look on the flat pad next to the distributor for more stamped build data.

cool found everything except the vin number quote "The engine block vin can be either located at the transmission interface by the oil sender unit, or at the right front pad below the starter. But not both locations on a particular engine. And sometimes there is no vin marked on the block if it was an early production unit."

Do i look from the back of the engine , underneath ., where do i look exactly it could be staring at me and i still probably woudnt know sorry to ask dumb questions but its driving me nuts   

Please i clickeds on the links but cant interpret the picture does someone out there have another  picture of its location and or a description for dummies like myself there is so much stuff on my engine that may be partially blocking it myself  , thanks Jase

Find the oil pressure sender unit at the top rear of the engine. If the serial number is stamped there look to the right of the sender unit. The photo below shows the exact location.

Dan's on to something there.  I'm not as up on '68s as the '69s, but from what I've read on here only the HP engines were stamped with the Special Order number (which corresponds to the fender tag and not the VIN tag).

With non-HP engines like yours, AFAIK there's no way to match up an engine to a particular vehicle - just a date code range.

My particular engine (383 4-bbl) has a serial number (by the oil pressure sender unit) that matches the 4-speed transmission serial number, but not the fender tag. But the transmission does have the properly stamped number matching the vin. See thread http://www.dodgecharger.com/forum/index.php/topic,38316.0.html.     1968's are special in many ways....

Geno, this is the only place I have ever read anyone post that a number besides the VIN was stamped on the block or that non HP engines were not stamped. Neither assertion makes any sense to me. I have yet to see anyone post a picture on any board of the SO number, instead of the VIN, being stamped on a 68 block or a factory source that cites the SO number was stamped on the block. If anyone has this info, please post it.

On a 68 with automatic tranny, both numbers will be next to each other on the back of the block and the front of the tranny by the oil sending unit. On a manual tranny car, the VIN will be on a pad on the passenger's side.

Doug,

You're right about the VIN rather than the SO number.  That's what I get for making a post while on vacation. 

I do, however, still believe that only the HP engines had a stamping based on what I've read on the board.  Could be wrong about that too though, I suppose...

Actually Dan's car holds the key to a couple of questions...

1) No documented 383-4bbl HP engines have been found in 68 Chargers to my knowledge. Is his pad stamped HP? If no then we know the 68 Charger 383-4speed cars did not receive the HP engine like they did in 69 and 70. This can be verified by a broadcast sheet if one exists.
2) If his car is not stamped HP, then we know that non-HP engines were stamped with a VIN.

Guys,

My take on this is that some '68's had a stamped engine vin,  some had a stamped SO number and some had neither. My engine and transmission have matching SO numbers (which do not match the fender tag), but the transmission does has the correct fender tag number stamped on the casing. I will endeavor to get some current photos of all numbers from the car so there is no doubt. 

Dan

P.S. The pad is blank , i.e., no stamping at all)

  OK so i cleaned around the oil sender unit and the transmission bellhousing and they look as clean as a whistle no sign of any numbers aaaarrggh   ( thanks for evryones help and ideas though ) wher do i look for numbers on the transmission ( probably left myself open with that question for some funny replies   Jase
