Hey all,

Does anyone know how many SLR & SLR 5000 there was made?

 

Also was the "HR" engine prefix for the SLR only or all L32 Torana's?

 

Trying to get some history on a car I own.

 

Cheers

No idea on build numbers but HR was the prefix for any 253/4.2 L32 Torana.

Thanks Dr Terry.

 

From what I understand HR (High Com) & HS (Low Comp) were the L32 prefix

 

Was HR only on SLR L32 or was it any L32?

 

Just trying to gather info on a car I have.

Cheers

Joe

L32 is the RPO code for the high comp 253 V8

 

L33 would be the RPO code for a low comp 253 except I've never seen one in a Torana, it's possible some export models got a low compression engine but they were mostly used in commercial vehicles.

 

The "H" prefix signifies an LH, LX or early UC Torana red motor. All H prefix engines came out in a Torana, although not all Torana engines had an H prefix...

 

The second letter "R" signifies a high comp 253 V8, so no, they weren't only used in SL/Rs. Any 253 V8 Torana would've had a "HR" prefix.

 

If you're really looking to gather information on your car in particular then I'd suggest talking to Holden Historical Services about ordering a production report. They're well worth the money IMO.

[Dr Terry]

Correct, L32 is the hi-comp 253/4.2 V8 & L33 is the lo-comp version, but to my knowledge the L33 was never offered in a Torana, so I very much doubt that the prefix HS ever existed.

 

AFAIK it was only offered in the HQ/HJ with a QS prefix (or 11QS for a base Statesman, which would have been ultra rare).

Thanks for the info gents.

 

I did have a production report from HHS but it didn't give any other details that I didn't already know except for the car being sold at a John A Gilbert Dealership in Camperdown.in May 1974

 

I was told by RMS that this car was first registered in NSW in 1992 and then cancelled in 1993. From what I know its been sitting in a container ever since. Trying to find out where its been beforehand is very hard.

 

If it wasn't a genuine SLR I wouldn't care so much but I think trying to find its history would be beneficial.

 

I'll keep trying 

[Bigfella237]

So would that be Holden dealer number 025?

 

It's a bit funny that it was sold in Sydney in 1974 but not rego'd in NSW until 1992. I'd guess that means it went interstate, or perhaps had the wrong dealer code attributed to the sale?

 

I can't remember the details but I believe one of the big Torana clubs in Melbourne had registration records for Victorian registered SL/Rs (if it even was), hopefully somebody else here has a better memory than me?

[Mikehunt2022]

It didnt have a dealer code. Just says John A Gilbert PTY LTD Camperdown.

 

I found it strange also. My only thought was it was purchased interstate also. Seems a little un real to be sitting for 20 years unregistered and then registered in 92 and cancelled in 93

 

It is a Melbourne built car after all.

[Bigfella237]

That doesn't mean anything... with the exception of a couple of early prototypes (which I believe were built in Adelaide), all LH, LX & UC were built in Melbourne.

[Mikehunt2022]

Oh right I must be wrong but always thought the A or B or S or M in front of the Chassis number (and on the tag) referred to its assembly location?

[Bigfella237]

The letter on the end of the chassis number denotes the build plant, as in "M" for Melbourne.

 

The leading letter denotes the ADR (Australian Design Rules) revision. Whenever there was a change (or addition) of ADRs part-way through a model run they started a new revision.

 

So you knew that all "ALHxxxxxxM" cars complied to one set of ADRs, and all "BLHxxxxxxM" cars to another, as there could be different parts required to meet different ADRs.

Copy that

 

So correct me if I'm wrong. The numbers after the "ALH" are in numerical order? Say example ALH004001M was the 4001st built in Melbourne?

[Bigfella237]

Well, yes and no.

 

For the most part I'd say yes, but it's not an exact science. The chassis numbers were stamped sequentially early in the body assembly process but the bodies weren't necessarily placed on the assembly line in sequential order.

 

Plus, if there was a problem with a particular car it would be pulled off the line to keep things moving, then repaired and re-inserted later on. Or if it needed personal attention (race shells, special builds "walked down the line", etc.) then it may not go on the line until much later.

Ok, cool thank you
