1968 Numbers matching?

[gasoline_24]

I think he is referring to the pad just above the oil pan on the side of the block.  In 68 this should be blank.  In 69 and later years they would stamp the entire vin here.  On the 68 they either did or did not have the partial vin on the rear of the block on the top of the block by the oil sending unit.  Yours was stamped on the tranny, so it should have also received one on the block.  I am not sure if some missed and only stamped one or the other, but that is possible.

Could it have been a warranty block? I was under the impression that warranty blocks didn't have stamps.

A question I have been scared to ask....

[toxicswan]

All 68-70 Big Block heads are casting #2843906.

All are 2.08 Intake valves, 1.74 exhaust valves

No difference in ports, valve sizes etc.

The 67 (67 Model Year) 440HP only head is 2780915. It has a 1.74 exhaust valve where all the other big block heads in 67 had a 1.60 exhaust valve.....also a 2780915 casting number.

An early 68 car would have 67 dates on the  2843906 casting.

Here is the casting on one head:



Here is the casting on the intake: (date is 6/14/67)


Here are the stamp and tag off the carb: (178th day is June 27th)



Stamp on oil pan:


BUT: look at the casting on the header:




WHAT DOES IT ALL MEAN?!

The guy who has done a lot of the work on the car found a stamp on the driver side of the block on milled surface where the oil pan attaches that matches the last 8 of the VIN.

The above quote is the only part I found confusing/questionable?

(vehicle identification number) VIN# - XS29L8B104863
(scheduled production date) SPD - 816 ** Wednesday, August 16, 1967 **
(shipping order number) SO# - 101437
core support & trunk lip should be stamped "B8X101437"

Block Cast - 4/4/67
Short Block Assembly - PT 440 2230 1015 (PT = Trenton Engine plant 440 = cu. in. 2230 =  9/5/67 1015 = unit number)
Engine Assembly - D 440 9 5 (D = 1968 model year 440 = cu. in. 9 5 = September 5th)

one head is dated 4/25/67
#402 oil pan correct for '68 Charger R/T

carb
Carter AVS #4429S dated F7 = 6/67
tag #38 = Chrysler part # 2863838

exhaust manifolds
2806900 date looks like 1/1/69
2843992 date looks like 2/14/69

IMO the engine is out of a early production '68 c-body 350hp 440. (non-HP)
----- HP 440 (375hp) engines are VIN stamped in model year 1968, non-HP 440 (350hp) engines are NOT VIN stamped in model year 1968.

The exhaust manifolds are from a '69 model year 383 or 440.

After listening in to countless discussions on numerous forums about '68 block VIN's I have come to the conclusion that there ain't no set rules. Some folks have originals with no VIN, other with top or side VIN's.

One explanation deals with model year versus calendar year and the government mandate being for a calendar year while model production began in September of '67 so there was no actual government VIN mandate until 1-1-'68.

Thanks for the info on the engine serial number and the carb. The manifolds are both dated "68" not "69", but shouldn't they be dated "67"? And after removing the paint on the front of the block you can faintly see an "HP" next to the 440. I was told that there is a way to use acid to bring it out more. You can hardly see it. I think the block must have been decked. But regardless, the block was assembled about 3 weeks later than the SPD. Is that possible?

[John_Kunkel]

Decking the B block will often diminish/obliterate the stampings but not the RB.

Muratic acid will highlight the shallow-stamped numbers but it's dangerous to use and must be thoroughly rinsed off with lots of clear water.

The Carb is correct for a 68 440 HP Automatic

"RB"?

[maxwellwedge]

RB = Raised Block

413/426 wedge/440   and there was an RB 383 once 1959-1960

B  =  361, 383 400.  I think there was a 350 a long time ago
