i am just wondering what is the weight of heaviest torana from the factory is?? . I ask this because my engineer has told me that you times the vehicle weight by 0.294 and it will give you the maximum engine size allowable .
eg -vehicle mass 1250kg x 0.294 =367.5 eng capacity maximum
vehicle weights, what is the heaviest Torana?

1204kg seems to be the recognised heaviest weight used by licensing authorities. This is from reading other peoples respected comments on this forum.

hmmm. he couldn't remember exactly but he was pretty sure that the 355 strokers were too big by 3/5ths of bugger all. He did add that they were going to possibly change to a national standard and that the power to weight ratio may be increased a small amount. oh well if i end up stroking my 5ltr it looks like it wont be engineered. cheers mate.

I had my LX weighed for engineering and the fat pig came in at 1360kg with a LS1 and T-56. This is the mass weight they used.

you would think they should go off the weight the vehicle is at time of inspection . i'll bet most ppls Torys are heavier than standard with 9" diffs and alike!!

The NCOP that applies in WA contains the following statement.
The actual tare of the car is not relevant. Each licencing authority appears to have their own figure. You may be able to argue that there figure is wrong and use a figure published by GMH, however I expect you would drown in red tape.
The heaviest figure I have seen in print is for a 6 cyl LX hatch which is 1213 kg. However the Perth Technical section use 1204 kg for both the hatch and sedan.
It is my understanding NSW have similar wording and rules.
This is a sample of weights posted by GMH355. For memory this is an extract from a NSW document. It appears that NSW use 1205 kg.
Maximum engine capacity is based on the original tare of the model vehicle fitted the the largest engine available without optional accessories.

eg -vehicle mass 1250kg x 0.294 =367.5 eng capacity maximum
Id assume the heaviest torana that came out of the factory would have fitted a 5L v8, auto, ac and towbar...and whatever other weighty options were available.
Its not clear how you engineers formula works? does the mass include the mass of the motor you are going to put into it?, or is it the mass of the vehicle without a motor in it.
I would have thought from an engineering point of view the actual weight of the motor would be more important, but I suppose the capacity sort of looks after that anyway.

Perhaps some authorities work with that rule, but isnt it about whether the car/chassis is designed for the weight?
Im sure there would be lots of ways(legitimate or not) of getting the car's overall mass up by a couple of hundred kilos for the inspection just so one could put in a higher capacity motor.

I know my hatch needs to go on a diet, weighed in at 3181 at the drags last weekend which is around 1450kgs. Although i was carrying around 60 litres of fuel.

In ACT the heaviest weight listed for an LX torana is 1275kg. This allows for a 6.3L. I actually have copies of the original Holden sales documents for the vehicles when sold. This is where the original ACT weights derived from. ACT also applies the NCOP guidelines.

Can do. Pm me your e-mail address. I will scan them for you but the copies are very old and faded and may not scan well. They are very factual and like I said, used by the ACT so you should be able to convince your engineer.

if you cant persuade your engineer, maybe try going thru a different one. The first engineer i took mine to would not pass my conversion, capacity to weight rules were 3 times the weight and the car was about 80kg too light. However i went thru a different engineer and he said 4 times the weight no worries and signed it off.

I put an LX 4 door A9X over the pits in WA (a few years ago) and the WA inspector showed me an old Torana list of weights and the 4 door A9X was quoted as 1315 KG.
Well that's what his documentation had on it, I guess it's only a piece of paper that somebody typed up in the late 70's.
Catch U all Later.

Do you have any paperwork to backup the figures?
If you have access to some sort of official documentation then there is a chance of getting the rego departments to accept the figures.

weights are in the Appendix at the back of Dr Terry's book, 60 years of Holden.

Thanks for the info, I have the book but I had not read the appendix. I expected that information to be in the Torana section along with the other stats
I doubt the book would be sufficient however it is a start. Dr Terry may have access to an official document or it may be possible to get the specifications from Holden.
In WA 1306 kg will give.
Naturally aspirated
1306 * 5 = 6530 cc (398 ci)
Turbo/Supercharged
1306 * 3 = 3918 cc (239 ci)

I would think that Dr Terry might have this info as his book details pretty much every model, and variant Holden ever made..
Dt T.. over to you.

This is what the ACT uses. As I posted earlier, it comes from original Holden documents from the 70's. It refers to tare weight not kerb weight. Heaviest version is SL/R 5000 1275kg.
