Here is the info from the pages:

[h=2]198 V6 Numbers[/h]
These numbers are by no means complete. If you have more
numbers or information on 198's please email
me.

Located on the front of the block, drivers side, just below the head

[h=4]Engine Number[/h]
First Digit: Year

• I -62
• J -63

Second through Fifth Digits: location cast and car serial number

• 25104

More on the engine numbers; a 6 with a bar over it ( 6 ) means a 6 cyl with a .010" oversize cylinder bore engine.


All together the engine number would appear as follows: I625104

[h=4]Casting Numbers: On the back of the motor at the top, casting numbers[/h]

• GM 1349430

[HR][/HR]

Intake casting numbers:

• 1851578-2

"-2" Denotes a 2 barrel intake.

Note on manifold numbers; this number is the only casting number I have seen
for 198's, there may be others. If there are and you know of them please email
me.

[h=2]225 V-6 Numbers[/h]

• 1358435
• 1396736
• 1381623
• 1375162
• 991503

From my present info, these are all the 225 V-6 block casting numbers.

[HR][/HR]

[h=4]Intake casting numbers:[/h]

• 1 barrel : 1381552
• 2 barrel : 1378704

[h=4]225 v-6 engine id codes: Buick special 64-67 (1 and 2 bbl.)[/h]

• 1964 = KH [between branches of right exhaust manifold]
• 1965 = LH [engine number on the right front face of the crankcase, just
  below cylinder head]
• 1966 = MH [as '65 above]
• 1967 = NH [as '65 above]

...so the codes are either on the side or front of the block just under the
cylinder head.

(I have heard rumors of a few engines produced in '63).

All are listed as 9.0-1 comp. ratio.

The engine codes seem to indicate that the first letter is the engine year,
while the second letter is the comp ratio (9.0-1). The two letters together
identify this engine as a 225 V-6, as the same year letter was used by Buick for
all engine types '64-'71 (v-6, v-8) but the second comp ratio code letter varied
between different engine types with the same comp ratio (i.e., a '64 V-6 comp
ratio 9.0-1 is a "KH", while a '64 300 V-8 comp ratio 9.0-1 is a "KL").

[h=4]From "Service Manual Jeep Universal Series";[/h]
"The engine code number shown in Fig A-4 is provided to identify the
Dauntless V6-225 engine. The meaning of the coded letters and numbers that are
stamped on the right front face of the crankcase, just below the rocker arm
cover, between exhaust manifold ports, is given below:

Letter to designate market:

• M-Military
• E-Export
• D-Domestic

Letter to designate year Built:

• N-1967
• P-1968
• R-1969
• S-1970
• T-1971

Letter to designate Engine Compression Ratio:

• H-V6-225 9.0 to 1 C.R. (2bbl carb)
• Y-V6-225 9.0 to 1 Marine (Low Profile) (2 bbl carb)
• Z-V6-225 9.0 to1 Marine (High Profile) 2bbl carb
• K V6-225 7.6 to 1 (2bbl carb)
• L V6-225 7.4 to 1 (2bbl carb)

The next three numbers are then the day of the year noted in the second
position.

In 1965, some Jeep V-6's are listed as coded "KLH" (and maybe'64 or '66
engines as well, still trying to research this).

Sometime '71 to '74 Buick bought the 225 V-6 back from AMC Jeep and rebored
to 231 cu in. The engine stayed odd-fire until sometime in early or mid '77,
when the engine was changed to even-fire by revising the crank throws (and other
modifications). The odd-fire V-6 was gone forever.

I have no info of Buick using the "new" V-6 in '74; first use seems to be in
the '75 models. I haven't seen any info that shows these engines in production
for '72, '73, or '74 (of any firing order or displacement). All Buick
231 block casting numbers from my info begin with the numbers 124, 125, 126, or
255.

There are after market intake manifolds available for the 225 V-6. Two are
the Weiand four barrel intake part #7541 and the Offenhauser 360. Even-fire 231
intakes have been said to work if you use a '78 or older intake gasket. Be
advised that a four-barrel upgrade may cost some low-end horsepower. Engine
parts are said to be available from Kenne-Bell and Kanter Auto Parts, among
others. Information on both companies is available via the internet.

some personal opinions are expressed. Not responsible for errors, as the weeding
of the garden of knowledge to find the flower of truth is a never-ending quest.

I have tools that allow me to capture web pages and store them... I kept some from my research times as I know they come and go.

 

That looks correct based on the numbers you show.
