Bit of a bugger to have a typeo, it could of been 2499lbs.
Would think it would be heavier with the V8.

The Red 308 V8 is only 22Kg more Heavier  than the Red 202 6Cyl

You would think that if GMH rego one back in 1972, it would open the door to V8 LJ. I thought ???

[Bullet]

I agree with you Al, but will Vic roads come to the party, that's the big question.
Was there a news paper artical or anything recording the rego or was is hush hush at the time?

Cheers Bullet

I have a copy of the original rego papers from Vic Roads for LGN307, I own the Number Plates, the Engine was a QT Engine, says 308  and says Eight in Engine part on rego papers, and 4.0" Bore and 51 HP for Horsepower

 

Red 202 6 Cyl HP on Vic Road rego papers is 31 HP

Surely it would be more than 51hp?
What you have you would think would be enough proof, in my eyes anyway.

[Bullet]

Does it say factory V8 on the papers anywhere Al?

[xu2308]

I think we are talking BHP from that time frame I reckon, that's why its 51 HP (BHP my bet)

It says Rego by GMH and it says its a Brand New Car on the Rego Papers

[Dr Terry]

Those HP figures are only RAC taxable horsepower, nothing to do with the HP that the engine produces.

 

It is calculated by using the bore dimension & number of cylinders only.

you have Dry or Wet Weight too

[Dr Terry]

GM-H's official weight difference between a 6-cyl HT/HG Kingswood & the 253 V8 version was 90lb (41 kg). This would include all ancillaries, flywheel & clutch etc. In the HQ series this difference was listed as 170lb (71 kg), but this would have included the Salisbury diff as well (HT V8 had a Banjo)

 

An XU1 engine would probably weigh slightly more than a stock 186/202, so when you consider the 3 carbies & the 2 exhaust headers, 35 kg would be an intelligent guesstimate. I find the 22 kg figure a little difficult to believe.

 

I was talking to Harry on this topic back in the 90s & he said at the time that his XU-1 V8 prototype was lighter & handled better than a stock 6-cyl XU-1. He said this was because the centre of gravity of the V8 was further rearwards than the 6-cyl & that he had fitted a fibreglass bonnet, which saved more weight than the difference between a 6-cyl & a V8.

If its 41kg, that is even better, need more weight to get the LJ up there to get a 308 V8 for rego status

Hi Al, if vic roads except Dr Terry's press release a 308 will make it easy, should be able to go to 336ci
1102 x 5 = 5510cc which converts to approx 336ci.

It's not 'my' press release, it is an official GM-H press release from the day of release of the original LC XU-1.

 

Dr Terry.

[xu2308]

Mark
remember you are talking LC for you, i believe the LJ are different weight to the LC Torana's

[Bullet]

Sorry Doc, I ment the one you supplied me a copy of :-)

Al, I thought they might group the two together but after reading one of the links that Dave put up I would say I'm wrong.
Guys like yourself know there are many many differences between the two but the goose behind the counter at vic roads wouldn't have a clue. I suppose all they see is that one is an LC model and the other an LJ, they probably don't know the body shap is the same!

Cheers Bullet

I need to work. out the correct GMH weight for a 72 LJ GTR and add the 41kg, to get correct weight for a V8 LJ GTR

[Bullet]

Hey Guy's, just let ya know that Vic Roads approved my application to fit a 327ci chev in my LC.

 

Thanks again Dr Terry for the press release, i think it made all the difference.

 

Cheers Bullet

That's got to be good news for a few people especially you    

[xu2308]

Great News, Vic Roads 3 Cheers

Looks like every thing I have checked for LJ TARE weight is

LJ XU1 is 1048 kg  in The Holden Torana GTR-XU1 Book (The CAMS Doco stuff)

 

Spotlight on Holden Torana Book weight for

LJ XU1 is 1099.6 kg

 

Torana Tough Book from a sales Ad thingy from back in the day

LJ GTR is 1058.6 kg

 

Now the NCOP says the Original Tare weight has to be over 1100 kg to fit a 308 V8

Now if the LJ XU1 was Heavier than the LC XU1  then why does the weight not say this in these publications

 

The GMH Press Release for the LC XU1 says the Approx Kerb weight 2430 LBS that equal 1102.23 kg. So that is over the NCOP to get a 308 into a LC Torana, now if LJ XU1 is heavier then we need the GMH Press release for the LJ XU1 that includes the kerb weight to say that, the LC/LJ is the same as in body type etc, but will the engineer accept that for the NCOP thingy ???.

The problem is that Kerb weight is more than tare weight as it represents a car with a full tank of fuel.  Tare weight is with 10 litres of fuel. All mods are/should be based off tare weight not kerb weight.  Been down this path many a time before :-)

Edited by Redslur, 04 May 2015 - 12:14 PM.

[Dr Terry]

Virtually all weights that GM-H have published in their literature since 1948 are kerb weights.

Seems to me NCOP set the scale for 1100 kg for 5.0 Litre, So LC/LJ can not have a 5.0 Litre put in them, Crazy when there is a Chassis Kit made for that type of application and a upgrade to LX Discs and LX Calipers to handle the breaking and the LC/LJ is very close to the weight of 1100 kg any way.
