thanks again for that info baz , the paper work that i got with the vehical stipulates that a genuine xu1 crank is being used and a genuine xu1 camshaft , there are numbers and letters writen beside it 456" 11.59m lft ! my question now is - is this a normal camshaft , , . cheers

Hi

As I understand, he 186 XU-1 engine had its own crankshaft which was steel rather than cast iron, but so was the crank in the 186A. The cam grind appears to be the same as the "XJ" that was first made available for the '72 Bathurst LJs. The standard camshaft for the late 186 XU-1s and 202 XU-1s was the "the XH" which had a .429 (10.89mm) lift.

sorry to be a pain , im just trying to understand whats been done to this engine , so what you are saying this camshaft appears not to be a genuine xu1. cheers

Hi

It's impossible to say without physically looking at it. Sometimes people say "this engine has an XU-1 cam" when what they mean is that it has the same 'grind' or specifications as was fitted to an XU-1. The specs that you have provided suggests that what you have is the 'hotter' cam that was made available by Holden for the '72 Bathurst Specials. Some people find that this grind is not particularly 'streetable'. If it is an original Holden XJ cam - it should have an X and a J stamped on the front. You won't be able to tell whether it is an original without removing the timing cover.

Hi oz772

I suspect the crank was carried over from the 186S but I am sure Dr Terry will have more info.

Hi

Your oil pump would seem to be an aftermarket type made by JP Performance Products. The 100 MPH speedo is from a standard LC LJ Torana - they are often fitted when the 120 MPH is not available. Only the GTR and XU-1 had the 120 MPH type.

You shouldn't have any problems fitting the speedo cable if it is routed correctly. See picture below. I will try to measure mine tomorrow if that will help.

Hi

It looks like you have been given the wrong cable. I have measured 38" under the bonnet alone and I reckon there is 18 to 20" inside the cab. I don't have the dash out so that is as accurate as I can get.

Hope this helps

I thought I read on here that an optioned sports dash(For want of a better term)on a base model got the 100mph speedo and the 120mph speedo was exclusive to the GTR and XU-1.

Hi

I may have also thought that at one stage, but the parts catalogue doesn't support the view. Speedo VS11263 is only mentioned in relation to P/N 2818891 which is the guage type insturment assembly with Imperial Units. Having said that, I understand the the earlier cluster units, as fitted to the HBs, only had a 100 MPH speedo. Perhaps daf67 can check the dates on his cluster.

thank bazza , i took it back this morning and his boss gave me the right one , which is near twice a long ( didnt measure it ) i have just fitted it and havnt tacken it 4 a drive, should the 100mph speedo have the same calabration 4 the m21 oppose to its original 3 speed or auto what ever it was. cheers dave

Hi Dave

Your speedo should be correct as long as you have the right coloured drive to match your diff ratio and wheel diameter.

Cheers

If an Admin sees this post - can you put this thread in the correct forum please?

Hi wldgtr

The VIN of that car would be 8D11LDH297878J. It was completed on 16/11/73 and sold by dealer 557 (?? NSW) during Jan '74. The original engine was JL436014.

The colour is/was Glacier White and the trim is black vinyl

The Chassis Number accords datewise with the others but be sure that the Chassis Number on the ADR tag is the same as the one stamped on the inner passenger side guard.

No - it isn't possible to have a VIN tag legally replicated.

Cheers
