Like Greg..I am over the experts who take as gospel all the written word..No personal attacks Brad..just stating what I know being involved in the game at the time...(Pete Geoghean once stated at a 1971 Easter Bathurst meeting that he retired because of an electrical problem...it was later reveiled a rod came out and knocked his alternator off...but I am sure you were convinced he had an electrical problem...I rest my case.)..not what was written to the punters out there who believe everything that they read. NOS is right..get a L34 for a real thrill...less made than GTHO P3s...thats gotta count for something.

Everybody talks about the Bathurst specials of 71, 72, & 73.
Have we all forgotten about the original Bathurst XU1.
That being the first batch ever produced.
The car was released in August 1970 and raced in the 500 later that year.
Anyone owning a car produced before Bathurst in 1970, to me has a "special" car indeed. Just how rare would one be now?

By the way, I'm pretty sure the fine splined Diffs made their Debut appearace in the homologated '72 'Bathurst' cars.

But if I'm wrong, I don't wish to be mentally tortured like those who have gone before me.

Nice story about 'Pete' Rory.
Like Bond at AIR after he crashed the XU1 into the wall.
Told Harry he had a steering problem after he hit a rock.

John.

Better one John...I was there because they were running cut slick Dunlops and Denis asked me to help....Bondy came back and told Harry the car wasnt that bad after the 72 crash.."Its just got a bumper rubbing on the guard"...Harry later said..He didnt tell me it was the front bumper rubbing on the back guard!...Of course it wasnt that bad but we pissed ourselves..Great humour from some of those guys..

Hi bradxu-1

Welcome to the forum. Based on your input thus far, I am putting you on my "People Who Have XU-1 Credibility" list.

It would be nice if you could stick around. If some of us ordinary punters (and experts) don't accept everything you say as gospel - your undoubted expertise and input will still add to the body of knowledge on our favourite subject.

loneoranger the fine splines were first introduced on the 73 bathurst car ,
just another reason why the 73 was a bit more special , along with larger valves,
port work manifold and head and a set of extractors to replace the cast headers ,etc, the 73 bathurst was capable of 138 mph or so .

cheers

Your right there Rory and NOS. L34's will rip the ass right out of any XU-1, bathurst special or not!

Maybe you are thinking 73 for the cam Brad, All those items were free from then but non homolog cams were a big no no in 72.

That actually happened..Got a better one..was waiting at Kingsford Smith airport with Chris Heyer (VW Passat/Golf)to jump on a plane to go to the Sandown meeting in early 75..John Goss turns up at the airport..he had won Bathurst previously...in full race suit..gloves and helmet under his arm. He was such a tosser! We all tried to hide so he wouldn't come up and talk to us.

The reason I know this story in the article matches up, is that Peter Brock's cam was nicked from the engine shop workbench at HDT. I know a guy who used to work for HDT (I bought an ex race car which he built) and he also used to contract build his own cars (for privateers) on the HDT premisis. The XJ was an optional cam, which is what they resorted to. I had this guy come here one night and spoke with him and the cars owner about the car at lenght, as you do. He said the 'works' guys had money and spares coming out their ass but his privateer could only just afford to get on the track. This story has been confirmed by many sorces too.

Dosen't really matter anyway, all in the past, isn't it!

Brad

this thread is gold. just when the fire dies down a little, along comes a gust of wind and sparks it right up again!
Rory, just out of curiosity, what did you do in the 70s with the race cars? were you a mechanic or something? You sound like you've got some interesting information tucked away in your brain.

Originally I was National Bell Helmets manager for Frank Matich, then did Pirelli M/C tyre set up for him, then went to Dunlop Racing..mainly bikes but was always used at most car race meetings as I was single and would piss off to Wanaroo for example at the drop of a hat. Helped run Chris Heyers race team as well on the side, VW Passat and Golf in series production. My brother was team mamanger for Frank Matichs Race team , Sportscars SR3/4 and F5000.(A50/51/52/53)..now there is a man that has some stories that some people would love to hear.

And who was the HDT driver that put a fire hose through a motel room bedroom window and waited until his team mate got home with a bird he pulled at the club that night....then held off until they were in bed and turned it on flat out???..It was so bloody powerful...it smashed holes in the gyprock ceiling when it was thrashing about the room...about $1000 worth the damage..that was a lot of $ in the 1970s. :clap:

On the DOCUMENTATED 150 1973 cars...there were shit loads of others made..I have seen 3 engines pulled down with all the same bore cut outs etc as the documemted 150...what every one misses is GMH had to provide to CAMS 150 VIN numbers.....so they just counted back from the last one to get the 150...mine was 7.8.73 and had the eared sump..block cut out the whole shooting match in the engine department.the head ports were as spec for 73 Service Release.but its number wasnt on the LIST..

See just released AMC No.32 Letters in Muscle Car Assist page 33 re : Wanted Bathurst XU1 Info. There another one not on the list.

hi there loneoranger
i have a lcxu1 8/70
this will make a interesting topic
i bought the car from a car dealership in 1982 i test drove the car and the car would not rev over 4000rpm
i bought the car and got it home
the motor was 3100x orignal
when the problem was worked out no lobes on the camshaft
the cam shaft the came out of it was a hx cam
the diff had a noise in it and i pulled it out to inspect and the axles wore fine spline with a 3.36 lsd
its good to see that someone is looking at the august 70s as the starting of something
the car is very interesting as 000 dealer number and sold in the 10/70
thanks for your comments re the (70 bathurst)

Dealer 000 I thought was export or internal sales/use?..Might pay to dig deeper..you might have something special..look for roll cage bolt holes.

I wonder if the cam lobes were shaved deliberately.. and the car was used as a sales demonstration/test drive for the dealer. To keep the joyriders from going crazy! You never know

Just for nostalgic reasons, here is a pic of my first car... a 1973 Bathurst XU-1.
Yeah it has flared guards and an SLR type spoiler but it's the real deal. When I blew 2nd gear in the car the bloke who fixed it told me that I was very lucky because it still had the original bathurst gear box in it. I never thought much of it until now....did they put special geraboxes in them or did the bloke just realise because of the numbers that it was from a bathurst model?

He was quite adamant that he could have ripped me off and said that the box was stuffed and I needed a new one..only to repair and sell the original for lots of cash.

Now remember this was in 1987, when most XU-1s cost around $4 - 5 thou. I know the car was a genuine Bathurst model, but can you tell a "bathurst" Gera box from from a standard one?

Over to the older and wiser members.

the bathurst xu1 camshafts will wear quicker than the normal xu1 cam shaft ...

the 73 bathurst also had an option '484' cluster gear , all other ljxu1,s had the 899 cluster , this was designed so brocky could go flat out in 3rd gear over the mountain , without this 3rd was too low and 4th was too high..

So was this only available to the bathurst model or was it a general option to '73 XU-1's?

Sorry to sort of steal the thread...is this worhty of it's own thread? pretty interesting.
