V8 Engine Numbers

Hi 1tunner. The engine you have is a 308 & came out of a late HQ Statesman. The 11 prefix refers to the Statesman origin, the QT means HQ/J/X/Z 308, & the 243608 is the serial number. The fact that it has a Tri-Matic behind it, means it could only be an HQ engine & the 243,000 serial number places it around late 1973 or ealy 1974.

The other way to tell a 253 from a 308 is the block casting number near the LH (passengers side) engine mount. It will have 253 or 308 cast in numbers about 40 mm in size.

Hope this helps, (Dr Terry)'

Hi Dr Terry I have a hx

Hi Dr Terry
I have a hx premier but wondering if the motor is different to the original the engine # is QR 937607 and #on the front above water pump is 17b8 the funny thing is that its a red motor but the paint is peeling off and revealing a blue paint on the heads and donk, which tells me it must have originally been a blue motor but I though that only the early commodores came out blue but then the # wouldn't be a QR I would've thought.Are you able to help out at all. Regards Cheffy

V8 engine numbers for HQ/J /X and red HZ

Your engine is a 308 it is originally out of a Statesman. this is how it works.

your engine code as listed is.

11QT243608, it's the first for digits that give you the info you need.the rest are build number. The numbers 11 or 12 are code for Statesman fitted, (as far as I know the Statesman engines where the only one's to receive a number in front of the letter code), the letters "QT" mean 308cui, "QR" high comp 253 and "QS" low comp 253 V8. you have a engine that is getting harder to find that being a tri-matic block as most avalible now are turbo pattern (chev pattern). hope this help's you out.'

308 V8 Engine Serial Numbers

Hey guys, Alan is my name and so far today I've learned heaps from your site but still have a way to go. My situation is that I've bought an old Ramsey ski boat and am in the process of fitting another engine as the boat came without! I have picked up a 308, serial number 11QT837583 AND MY PROBLEM IS :- That the rear engine mount from the previous engine does not fit the new engine and I would like to identify it in order to order the correct mountings.
My engine was previously coupled to an automatic and the locating pins are larger in diameter and sit higher on the block the original engine. Hope to hear from somebody soon,
Alan.

Alan's V8 Ski Boat Motor

You have either a Trimatic Block and your bellhousing (for want of a better name) is a Turbo (Chev) pattern or vice versa.

engine number on a 253

hi people can any ony tell me what my 253 originally came out of the engine no is QR610335 any help would be greatlly appreiated thanks jimbo

253 engine number

I can tell you that the QR prefixed 253's came out in HQ-HZ Holdens.

As yours starts with a "6" I would guestimate the it is late HJ or a HX engine.

There is a date code cast in to the engine block that will tell you exactly what day, month and year the block was cast.

It is located on the top front of the engine block. There is a little clock symbol near it.

It will be a 3 or 4 digit code with one letter in it and 2 or 3 numbers.

Post it up here when you find it and we will decipher it for you.

It won't tell you what model/body type it came out of (ie Monaro, Premier, Kingswood, sedan, ute, wagon etc) but based on the cast date you will know what series it was from ie HJ, HX etc.

Hi guys, Can you tell me where engine no VR334798 came from.

This blue 253 is in my mates 81 WB ute It appears to be not the original engine so we are curious as to its origin.
The ute is a Kingswood auto with air and steer and a sports dash.
Any advise on this ute would be appreciated. Thanks

hi guys need to know if vt446886 is for a vk308 and also how to tell difference red to blue/black motor thanks

Vk 308

Hi .Going by that engine number it's commodore definately with a VT prefix and being 446886 from my reckoning it's 1984 so should be vk.Cast date on front of block would tell you definately. Spotting the difference between engines there are some giveaways. Red ( HQ to HZ/VB ) has the engine size cast only on the left hand side of the block above the starter where as blue and black have it cast on both sides. There is no difference in blocks between early black and blue as they were running at the same time ,first blacks in vk 1984 VT prefix ,same engines blue in wb 1984 WT prefix. later blacks(304) have 5.0 cast on the block rather than 308. Cheers.

Engine no. and cast date

I did a Vehicle information package (VIP) check on my car (which you can get its VIN/chassis and engine number without paying (VIC only), any other detail you'll have to pay it seems. Go to: https://www1.roads.v...

Panel van: The Chassis no. was recorded correctly, however I have no idea where the Engine no. is meant to be located (HZ panel van 253 - with cast date: 19C6 - being 19th March 1976). The Engine no. listed for the panel van is showing up in the VIP check as: VR55142.

Sedan: I just did a check for my HZ kingswood sedan (253 - cast date: 14J8 - being 14th Sept. 1978) and the Chassis no. was recorded incorrectly as BHZ214373, which should be a 'S' at the end rather than a '3'. The engine number is listed as: QR7244 (is it missing a number?)

Could someone tell me where to find the engine number, so l can double check that the information recorded with the Vic roads VIP is correct and also could someone let me know what both my engine numbers mean.

Cheers Fella's

Im confused

I recently brought a reconditioned 253 from a reputable shop

there is no engine number on it, and it shows no signs of having been tampered with.

the cast no appears to be 363 or 3G3 with the dial pointing to the 3 position

what does it mean?

steve

Confused Steve's Block

It is common for Holden V8 Engine Numbers to be removed during decking of the block.

The company SHOULD have stamped the original number (or one of their own if they are allowed to) back on it before selling it.

You can find out the original number by having it X-rayed.

Your Cast numbers identify it as a 3 July 73 or 83 block. You'll need to find out the engine number to identify the decade it was made in.

HTH.

Looking at earlier postings am i right that it was a HX that it came out of and that the block was cast 21/10/76

253 Red

Nearly right with reading the casting date,
the months start at letter A, that = Jan.,

but they skip the i because it looks like the number one
so working along ,H is Aug. miss the i go to J
this = Sept. 9 month ,so that makes your block 21/9/76

it came with a catergory 2 cerfictate of engine modifaction, the eng number VJ571*** ive done some reserch and think its a 304 block aposed to a 308??? would that require a C.O.C.???
It also has had the fuel lines and pump removed. so that only L.P.G can be used. they have gone back to what i think are L34 heads, because of the slopped markings on the front face, and how easy it is to access the spark plugs. it then runs a quadracarbie and mpeco gas system...... My question is what will i need to put it to fuel injection?

blue 253

just wondering if anyone could help me... looks like the engine number is VF222263 its definatly a blue 253 do you think it should be VR222263? and how can i find out what year/commodore it came from? cheers

engine number is VF222263

I'm tipping it is from a VC. But if you look HERE.
It shows you where the date stamp is.
It's an alphanumeric date code cast into the block.
The letters are the month, only the letter i is skipped(to avoid confusion)eg:Jan = A. Dec = M.
The last number is the year of the decade the motor was built.

Unless you know the engine number and can find that motor. I reckon you will just have to settle for a HT prefix block that is date stamped to suit your cars build date.
Cheers.

308 black motor

hi,could anyone tell me about my engine number,308 black starts with w ends in p

That is a WA Police

That is a WA Police number
NSW is N#######P
VIC is v#######P
and so on
Just means it was probally stolen recovered or the number was removed and unable to be recovered

WA Police number

Hi,
Yes I agree that it is a WA Police number, I have two here, 186 and 253.
But no it doesn't mean that it was stolen and recovered at all, it could be very likely to be a replacement block, these came unstamped until about 1971 in the case of XU-1's and some other models.
For these cars it was necessary to get the police to allocate a number to the new block unless some enterprising person decided to do it himself!

With V8's as already covered it was not uncommon to also have their numbers machined off when engine reconditioning.

Queenslands number is Q xxxxx P

I have seen a couple of police numbers for WA that start with W 9xxxx and the P at the end.
For comparison, I would be interested to find if anyone else has a similar numbered block?

And of course there are two numbers for NSW police in the case of the XU-1's NP ( Nasco Part ) and N xxxxxx P ( NSW police )

Mike

Black WP

Sounds like a West Australian Police Issue number...

Police Issue number

WT is WB commercial 308. So if you aren't mistaking the T for a P, WA police issue number would be my call too.
Here in Victoria the Police issued numbers are VP.

LH SS

MY ENG HAS A HT PREFIX AND THE DATE APPEARS TO BE 18F6 OR 018F6 IS THIS AN ORIGINAL BLOCK

HT is the prefix for LH & LX

HT is the prefix for LH & LX SLR5000 and LX SS L31 including A9X (except LH SLR5000 L34).
That prefix/date stamp combo says the block is from a 1976 LX SL/R or SS Torana, and was cast on 18th June 1976.

308 engine number

Im looking at buying a 308 with the engine number starting with 11TS i know 11 means statesman but what about TS.
Thanks Razz

Engine number

Ihave a 1978/79 SLE VB 5ltr commodore with a M21 4 speed box factory fitted. The engine number is VT6767 also original. What can you tell me about it ? Please.
I've been told it is a L34 motor as it has genuine "B" cast heads on it again original factory fitted. I've been led to believe it was an GMH executive vehicle when new and the motor was a HDT test motor for GMH to assess for warranty purposes for HDT to build and still have full warranty by GMH

You would need to check with

You would need to check with someone who is 100%, but AFAIK the B cast heads didn't come out until the VK run of Commodores. Before that, in the VH, and IIRC the VB & VC runs the HDT cars had X marked heads.
An L34 motor is prefixed HZ and was already collectible before B cast heads were even thought of. So what you have been told about the motor isn't right.
If you post up the inlet manifold part number I can tell you if it is the correct manifold that went with those heads. May not help, but may well indicate the assembly isn't factory.
Cheers.

WB 1 Tonner

I have purchased a WB 11/1980 plate and it has a red painted motor with Engine number starting with WL can any one tell me if this an original motor and is it?should it be a blue motor or red.

WB 1 tonner

Hi Holden fan,

More info required, a check of your compliance plate to see if it matches would be a good start.
The date cast date at the front of the block would be next.
WL is a WB 6cyl engine prefix,

Mike

ZL- ZR - ZT- 11ZT engine prefixes

Hi,
I wish all you guys would stop quoting QR and QT prefixes as covering all HZ Holdens, as it is frog [Naughty Pottyword]!

Mid to late HZ Holdens only ever had ZR and ZT prefix engines this includes the whole range including 11ZT for all the Statesman models including SLE.

Cast date at the back of the oil filter will be * M 3

A December 73 block does not have the three verticle block strengthening ribs.

Hi can any one help and tell me when this 308 engine block was made
QT 173892 regards louis

308 date

A 173xxx engine number is roughly from around the August September 1972 time frame.
If you want the exact day the block was cast post up the date code from the top front of the block behind the water pump and someone will tell you what it means.
Where to find the date code can be seen in THIS picture.
Cheers Paul.

Hi, whats the engine 11WT443673 mean?

308

Engine Number off a WB statesman

WB 1 Tonner

Hi, just bought a 1984 model 1 tonner with a 308 motor QT595465 but the date casting number looks like 25A0. Any info appreciated. Cheers

Three 0 eigth

you sure the casting is "0" ,
more likely should be 6

25A6 would be 25/1/1976

QT595465 is HQ to HZ range

WB 1 Tonner

Hi Midnight Cruiser,
checked casting again,definately 25A6. I think it might have a bodgey engine number,just doesn't look right!

Hmm ?

check your first post you had 25A0.............

it's the wrong engine for a WB tonner anyway,
it's a red 308
and WB Tonners didn't come with 308's,
only Blue 253's or 202's

308 1 Tonner

Definately 25AO and red motor 308. Could be 80 model with bodgy engine number.

Engine number

Hi just wondering if you could decipher a engine number for me it is a red 308 engine number QL257196 and the cast number is K122 and if you could figure what model car it was out of thanks you can email me back on tanya.clifford@bigpond.com.

Cheers
Anthony

Engine number

You might want to check the engine no again as a 308 would be QT not QL, if its QT257196 then it will be from a non Statesman HQ built in Nov 72
