Apology accepted rat catcher, though dont take me to serious.............




G/Day Don (ck1971)
The VIN DISK is,nt 100% accurate, there are typos. Once the VIN DISK is questioned, then every LC & LJ Torana is questioned. It is quite simply the most valuable bit of information any true LC or LJ enthiusast can get there hands on. The VIN DISC does,nt lie, though there are a couple of typos.

The VIN Bible tells us that Holden built 700 LC XU-1,s in 1970.

Why ?

Under the 1970 C.A.M.S. Series Production Rules a minimum of 700 were required. 200 for Eligibility and 500 for the updates, Baffled diff housing, Baffled fuel tank, 3.08 diff ratio etc etc. The rules that applied in 1970, 1971 & 1972 were basically indentical.

So you see Holden built 700 LC XU-1,s in 1970 because they were required to build 700 LC XU-1,s under the C.A.M.S. Rules. The same happened in 1971, Holden built 700 LC XU-1,s in 1971 because they were required to build 700 LC XU-1,s under the C.A.M.S. Rules. The initial batch of 200 being for Eligibility and the following 500 for homologation purposes.

1971
H2-2 Eligibility 200 required
1/1E 200 required
1/2E 300 required (Gearbox & Diff ratios required 100 cars per ratio)

700 required 700 built, its that simple..................

Every XU-1 Torana was built for a purpose, you only need to know what purpose your car served

The XU-1 Torana was built to race and if the race teams wanted a new part that may make there car go faster or handle better than Holden were required to build a minimum of 200 units. Its that simple..........

At the end of the day the VIN DISC does,nt lie

Hi all

I fully concur with Fly..

It is hardly a coincidence that we have both arrived at the production number of 1400 precisely for the LC and production numbers that are 'lock-step' with the numbers required for the various homologations in respect of the LJ. In the final analysis (after allowing for a small number of obvious input errors) I believe that the VIN disc is exceedingly accurate. The results should put to rest the inaccurate numbers that have been taken as 'gospel' since the Antoniou book.

According to C.A.M.S. this was the last production sheet they recieved from Holden

I had a hard time finding the 200 let alone 210...................








It was a battle finding 700 1971 LC XU-1,s let alone 733

As long as Holden built the cars the race teams got their bits....................

LOL, Ratcatcher!! Here we go again. I'll start. I've got one 10/70 Linamint LC

[FLY_AGAIN_XU-1]

I've got one 10/70 Linamint LC

G/Day Zook

Has your 10/70 got the baffled diff housing or a baffled fuel tank ?

Did any 8/70 XU-1,s recieve the baffled diff housing or baffled fuel tank ?

Did only the 9/70, 10/70 & 11/70 XU-1,s recieve the upgrades ?

Was the 3.08 diff ratio available in 1970 ?

There are still many questions that need to be answered and a whole heap more research on the LC XU-1 needed.

Let the research begin.....................

[FLY_AGAIN_XU-1]

This Service Letter is dated 3-9-1970 so any updates would have taken place after this date.
If you look closely you will notice a reference to the 3.08 diff ratio.
Certainly would have come in handy for Bathurst and also would have required a 100 cars to have been fitted with it................

G'day Fly

Original diff long gone but it was a 3.08.

Fuel tank is original and is baffled and does not have the additional baffle support which came later. Had a Bath 71 Car which had that support.

[71xu1]

My date coded diff for my 2 month 71 LC XU1 has no baffles and the tank has only the longitudional baffle.

[Zook]

My date coded diff for my 2 month 71 LC XU1 has no baffles

plus

i have a 8/70 9/70 9/70 and 10/70 and 3 of them cars had there original date matching diff housings in the when i got them but none of them are baffled,

That's an interesting one in light of the 3 Sept 70 Letter. Can you make any more sense of it Fly?

Ratcatcher, my car is on blocks undergoing rust repairs (for full restoration) at the moment. She's a slow process!!
