Always?

That pad and the way the number is stamped is identical to mine. In fact, the engine numbers are very close together. The last digit in my engine number sits slightly higher than the others, exactly per the '5' in this one. And the '1' is in the same position as well!

Yep that was me chucking in some sarcasm.

 

I believe the #3 cult want us to believe that all JP blocks should be #3 otherwise they are a restamp and all QL blocks are 2 & 6 and whatever else but not #3.

the dust samples should back soon to prove the pictures came from the same block.
Bloody light does not even play fair when taking pics. to at least give the same shade of paint colour.
 
Even some 3.3 blocks have a 3 , does that make them a JP , nope , probably got more to do with eng. # as already said.


Mold number looks like a 2

Actually, if someone was going to restamp; wouldn't you have to machine enough material off the pad to remove the original stampings. Surely that (if you could copy the factories machining method) the fresh machining would leave a sharp edge around the edge of the pad just where the casting texture is.

regards

( oz772 ) I was wondering if it is possible to tell what number yours has on the exhaust side of your 2/71 3100x block ? I have also been doing some research into the 186 3100x & CK blocks. The problem I am finding is the rareness of genuine blocks makes it difficult. With the genuine 1971 3100x blocks I have on record the last number certainly appears to be higher on them all as the 2 photos of the 1971 3100x blocks show. The ones I have on record also indicate the number 3 being present but certainly can not tell you with any certainty that all 3100x have the number 3 on the exhaust side yet.

If any one has a genuine 3100x or CK floating around I would certainly appreciate your help for my research. It appears so far the 3100x blocks also have the number 3 and the CK,s have quit a unique number never seen on any other 186...........

The so called 'unique codes' for CKs are likely to  be 6 or 2 or 3 or whatever,  just like a 73 Bathurst, 72 Bathurst or any other XU1 donk!!

I can guarantee that anyone who threatens or carries out anything violent at toranafest will have more than one person to deal with.

It's not the place for you to try and show how big your dick is. If you plan on being a tool (and your friends) do us all a favour and stay home.

I really don't want to get into this, but here goes. My 3100X block came from a 2/71 Adelaide plum dinger XU1 that was owned by a forum member here. I'm not mentioning names, as that is up to him. He totaled the car around 1978 after owning it for roughly six years. It then spent a short time in an HR (around 2 years) before being removed and stored as a bare block in his shed. I bought the block from him in 2010 (so, it was stored for 30 years). It was quite obviously untouched and original, with the striations on the unpainted pad and the last digit of the engine number sitting slightly higher than the others. The cast date is December 1970 in keeping with other 3100x blocks used in cars made in Feb 1971. Finally, with his agreement, I had it tested through another forum member to satisfy myself pad/number had never been tampered with. Which it hadn't. After all of that, the number on the inlet/exhaust side is '2'. And as I say, this block has been tested for authenticity.

I have no idea of the number on CK blocks. However, I have a D1 cast (April 1971) 186 block that has the number '6' on the inlet/exhaust side. It's engine number is 186P4xxxxx (the x's because I can't remember off the top of my head and it isn't with me at present).

That is getting very close to the end of regular production 186. Not long after this HG's got 173 and 202 as HG passenger had ceased production.

Yeah, I sort of figured it must have been very late. From memory, the cast date is around 17 April. It was in a HG Kingswood that was wrecked, and I grabbed it for ancillaries. I don't know whether this late batch was used for the CK blocks, or whether they were cast separately even later than this?

I don't know, never really had any need to look into it. GMH often did stockpile stuff prior to a major change but there would be nothing unusual in them casting 186 blocks specially for those last LC XU1's a few months after regular 186 production ceased. They did it for heads for LJ XU1.

GM-H cast those NG prefix 186 blocks in 1972 so it makes sense that 186 blocks for CK and NASCO would have been cast in the second half of 1971.

All CK blocks are cast E1,F1 and G1 with NASCO NG 186 blocks cast in the first two weeks of july 1972.

300 1971 CK,s in total Bruce. The majority being produced in September 1971 and having 9/71 ADR plates, a much smaller batch in October and having 10/71 ADR plates and a couple of handfuls in November/December having 11/71 ADR plates. Of the 300 CK,s produced, 100 had the 3.08 diff ratio fitted as per CAMS rules. Of the 300 CK,s produced I would estimate that maybe 10% or 30-40 cars are still with us today, and of these not all still have there original blocks which makes researching these cars and engines somewhat a difficult task. Such a shame for a little 186 3 litre powered car which took on the might and power of the 1971 GT HO phase III and beat it for the 1971 Manufactures Championship, earning it the title of the GIANT KILLER..............

 

LONG LIVE THE GIANT KILLING LC XU-1,s.........
