I'm I correct in that a 68 Hemi RR built in Nov 67 would have a 66 block? Also there would not be any ID #s connecting the drivetrain to the car, IE no stampings on the bellhousing mounting area or on the Auto trans? What would be on the front engine pad? 426 and a 67 date of assembly?

Look on the part of the pan rail that extends under the starter, there might be an engine number stamped there.

The top pad on a November '67 built car would have a late '67 assembly date.

I was told that a pre January 68 car would not have any engine serial #? Governement started the requirement in Jan 68. Is this correct?

It might have a '66 cast block due to the factory running off a batch and then slowly using them.

Some of the last year '71 Hemis have earlier cast blocks.

So what about the lack of a serial #, true?

Early '68 might or might not have a VIN stamped in the block/trans. Serial number will be on the pan rail under the starter.

440 and Hemi engine/trans were stamped with VIN at the start of 68 model year near oil sending unit. All others started on or about JAN 1 68 correct?

my 1968 original hemi charger has serial vin number stamped on top rail behind the oil pressure switch. my emgine is original cast date 10-31-1966. my car was assembled 3-04-1968

While the rumor exists of (very) early production examples lacking a VIN sequence stamping, I have never seen a verified example to prove it and plenty of early built cars that did have it. It's much more likely that your engine either has a VIN sequence stamping and you can't find it, or that the engine's been replaced at some point. Most 68 Hemi cars built prior to Jan 68 would have had either a 65 or a 66 casting block, these would have also been stamped with plant and assembly date info on the lower pan rail bell housing extension on the passenger side of the block. What is your cars scheduled production date?

IIRC all blocks would be before '67 in most '68 as ther were no Hemi's cast in '67

The car I'm looking at has B09 on the fender tag. Owner says it's an original drive train. States cars built before Jan 68 didn't have identification other than engine pad assembly date. Block is a 66 casting. Anybody know any history on this car?

I asked this question a week ago.I have a 1968 that the build date is 4-12-68.I have a motor that looks like it says 3-30-68.I seen on some website the block castings where in clumps,mostly 1966 I beileve like 6 differant castings dates and 65 had 2 late and 1968 had 3?My car is an export would it have a closer date or later?Thats why I figure mine might have the closer date,because of export?But was there a 3-30-68 casting or am I reading it wrong?There is no other #'s anywhere on pad or on railside or underneth.

This is simply not a correct statement. Keep in mind the owner (dealer?) is trying to make a sale.

If correct numbers are important to you I would not reccomend buying that car without having it looked at by someone knowledgable first (Galen Govier, Dave Wise, Myself, etc. pick one).

What are the dates for cast in 68 blocks?

January of 68 was when the first 68 blocks were cast. There is no known verified complete list of casting dates, just a compilation of casting dates people have gathered from blocks they have, there were quite a few dates over the year(s).

Then where would you look for the serial# stamp?

My 68 road runner was built on 10-20-68 and the block was cast 10-31-66 , it was my understanding that it was a request not a mandate that the vin # be put on the block. I have seen people in this forum say they have seen both motors with #'s and without. My hemi has a build date 0f 10-13-67 on the pad.

Request by whom?

The Federal government mandated that beinning in January 1968 all vehicles were to have the VIN sequence number stamped into the engine and transmission. However, Chrysler took it upon themselves to add them in the beggining of the 1968 production model year (mandated or not). As I said, I've seen several VERY early original cars that did have the VIN Sequence stampings, it makes sense to believe they all did or at least were supposed to have.

As far as reports of some finding no VIN sequence stampings on thier blocks, I wouldn't doubt there were some built that way, but have never seen a documented example that lacked it(such as a survivor or a complete original unmolested car that's never been appart etc.). Do some exist? Possibly, I'm just waiting to see someone step up with a good verifiable example before I commit to it as an absalute.

It's not a "Serial" #, it's the last portion of the cars VIN#. on a 1966 cast dated block it would normally be found on the rear bell housing mating surface of the upper block.

Later Hemi's were stamped on this pad (this example is blank)
