xu-1 Camshafts

The Antoniou book describes 7 camshafts that were fitted to LC an LJ XU-1s (see pages 114 and 115).
The last one mentioned, Part Number 9929247, was fitted to the '72 Bathurst and the '73 production run and was the last camshaft that was developed ex-factory.
I guess my question is "if not GMH - who produced the '73 Bathurst cam?

Accoding to the Antoniou book a 38-77 is correct for a '71 LC Bathurst. I would have thought yours should be a 55-94 which was '72 Bathurst to mid '73.

Hi UFO XU1Hey Bazza i was just talking to Dave Mclean about the "73 bathurst" cams & i think you will find Bazza that the class of racing changed from Series Production to Modified & the Camshaft was Open to run whatever you liked some companies they used were Waggot cams,Wade cams,Speco cams etc...thats when the HDT CARS ran the WEBBERS & THE TRIPPLE 2" SU'S with the camshaft to suit...
Hope that helps Bazza
cheers UFO XU-1
Yep - I get that impression from my readings, but the engines must have left the factory with CD Strombergs with some kind of cam.

Bazza
in the 70's he told me the xj 72 bathurst cam part no 9929247
with 456" valve lift.in late 73 they made a few cams for gmh
with 510" valve lift would have pushed the valve's down
inside the bore that's why the 73 bathurst cars had cutout
at top of bores.
xh cam as 429" valve lift which is a std lj xu1 cam

Thanks vin150cars
So that means that the info on page 115 of the Antoniou book is correct. I had read somewhere that it was wrong.
That still begs the question - what is the part number for the '73 Bathurst Special cam, the one that came fitted to the magic ??? Bathurst Specials?

Very informative and from reading, I believe, this subject will aways be "grey".
Good luck with your quest!

xh cam 429'' lift i still have it if you measure the height
of lobe you should get about 286'' then halve that figure
and add to 286'' you will get 429'' valve lift.
the cam as xh or hx stamped on it.
i have a xj cam in car now with 456'' valve lift made by clive cams
at about 4200 rpm you feel the power come on and lots of noise
through the exstractor's iam geting a bit old 69 but the car sounds good
and good to drive
i have two gaskets under the std tappet cover if you damage the
baffle you will use lot of oil it will get sucked though inlet manifold
73 tappet covers are hard to find

So in essence you are saying that the '73 Bathurst car came with the .429" lift cam?
The Antoniou book lists the .429" lift as GM part number 2823364. That part number has been in the parts catalogue since Feb 1972.
The .456" lift cam (GM part number 9929247) is described as the '72 Bath and the the standard cam up to the introduction of the '73 Bath Special cam (no part number given for the '73 Bath cam). 9929247 was definitely introduced from 31 Aug 1972.
Can someone with a 1973 edition of the NASCO parts catalogue provide the cam info please?

There is only one LJ XU1 camshaft listed in the green parts book (M37608) - part number 2823364.
In Fiv's book on page 161 - catalogue amendment dated 23 August 73 - there is a list of engine parts from engine No, JP386598 (no 1 of 150). There is no camshaft part No listed there.
To get Scooter's camshaft from Holden you needed part no 9935129, which is "Engine Block Complete (Short Motor) including Crankshaft, 'Camshaft', Timing Gears, Pistons, Pins, Rods, Timing Cover".
To my knowledge, no one on this site has provided Holden's Part Number for Scooter's camshaft, which makes be believe you couldn't buy this camshaft as an individual part from Holden. Maybe they just gave you Wade's phone number.
True or False?

I wonder what happened to 9929247 with the .456" lift that was recognised by CAMS on 29 Aug 1972?

Hi David,
I'm trying to find the pic I took of the XJ camshaft when it was pulled down..not being mechanically minded the XJ stuck in my mind remembering the XJ Jaguar...I thought it strange as no mention is made of it in the Antonio book. Anyway as I said b4 the engine was fitted with Repco pistons and had ALL the 73 bathurst mods.
PS: As for the master cyclinder it has been resleeved and will be on shortly.
cheers,
Peter aka scooter
