To be honest it would not be that difficult to get a set of stamps made up with the correct font.

In fact anyone with a bit of nouce could do it in their workshop.

I'm not a tool maker but I will venture to disagree with your prognosis Rob.

 

It may not be hard these days for workshops with scanners and computer controlled equipment but for the DIY in a home workshop/garage with run of the mill gear I think it would be much harder than it looks.

Dave.

 

I believe that stamps may have been made way before any computer was available.

In fact I am sure of it.

 

I could do it with the basic shit I have in  my shed.

But I dont have a steady enough hand or the patience.

Just been informed that 186P have cast dates of E1,F1,G1and H1 finish at 186P64#### here is a 186P464015.

Cheers

 

The highest known numbers are low 186P480xxx from 6/71 HG's which is one of the final HG passenger cars. The highest cast month on this will be early F but I suspect it'll probably be late D like the one posted or E. HQ restricted production began in April 1971 with volume starting within approx. 6 weeks later. There could also be a period of 161/186 and 173/202 crossover in HG commercials but I very much doubt you'll find any HG engines with G or H castings.

And you will need enough engine blocks to get samples of all the number fonts.

Enough pictures floating around on the interweb.

Will probably find the fonts are actually a documented type so a template to start would be easy to find.

Just need the height. 1 block required.

 

With all the effort some have gone through to produce fakes. I m surprised they havent already done this.

Perhaps they have though.

 

These days a dremel and some fine files and a magnifying glass would be about all you need.

Then an oxy and some oil to harden it up.

But they would be pretty good for a single used straight up.

I believe, from documentation I have read, GM-H made all their number and letter stamps in house.

That is why the average mechanic or engine reconditioner cannot get the same font stamps.

They will be to a certain font or style.

That way each character looks similar to those around it.

An old printer or signwriter would pick the style or font pretty much straight away.

 

For some reason you are saying its not possible.

It is entirely possible to do.

 

But only someone who wanted to hide something would really do it.

And who is to say that it hasnt already been done.

 

Only need 2 letters and 10 numerals.

And a block to line them up.

Don't get me wrong Rob i'm not saying it is impossible.  I just feel that it is not something that everyone with a few basic tools as you have previously outlined could easily whip up in their shed and get them to match perfectly to the original GH-H font style.

 

You wouldn't bother unless you had intent.

Simple, Genuine JP 202 blocks only have a 3 on the side ! ! ! This I am 100% certain of.


Bruce, when are you going to provide some proof of this...? You are beginning to sound like a broken record...

Even if you had the stamps. The broach marks on the pad will be gone when original number removed

Lets face it.

Anyone who has been a member here for long enough knows obvious stuff to check for.

But looking at some of the posts of pictures there are those who have been fooled or are trying to fool others.

A coat of paint over proper looking numbers will obviously fool some as other details have fooled others over the years.

 

If anyone was serious about buying something as expensive as an XU-1, they should be checking provenance, and getting expert advice.

 

After reading all the posts, and not having a vested interest in the subject, it appears that there are some making claims that cant be proven.

Now I have no idea why these claims are being made, but someone must have a vested interest in them becoming fact.

Maybe one day that reason may become obvious.

not buying into this mess....and buggered if I know....

 

but on a kindred tangent....in the latest Unique Cars mag, there is mention of a LX Hatchback that was recently sold at Auction.

It was owned by Fred James ( described as GMH Powerplant Engineer)...I am unaware if this gentleman is still with us, but if so, he would sort this out fairly quickly I would imagine. 

CAMS only recognises  what the manufacture has actioned, versus the competition requirements of the day.

The Engine Plant actually did the work..so they would be able to recall the ""3"" issue/importance?

 

Anyone know /know of this gent?

What about the measurement from the top of the pad to the bolt hole centre of the engine mount. You would have to machine the original numbers off,  maybe 20". the machining marks would have to be exact, sort of like a bullistics match. Take a long time to do that with a file and keep it all straight and copy the broaching marks; easy to check with a straight edge. There also appears to be a worn edge especially on the front of the pad of every pic I look at. i must admit the pic of that last eng number does look kind of odd, very close to the engine mount side of the pad. But I am no expert in this, just a suggestion. If i had a JP block I wouldn't like people saying it was a restamp, however, I would want to know if it was.    

regards

Fred James (RIP) has passed on, as I wanted to track down Fred my self, his Son was selling the Hatchback that was at Shannons Auction, Sad that Fred has gone as he would know the Holden Engines backwards, and the XW7 Engine.

This is absolutely spot on......     If what these people are saying is true, then it needs to be proven.... 

 

We are up to page 16 on this thread, and probably somewhere near that number on other threads surrounding this theory...     And in all that time, the 3 members that are pushing this theory have not put forward one bit of Documented Evidence or even a reference to where their information has come from...   They have not even posted photo's of their own JP motors identifying marks and numbers... 

 

It has been quite the contrary, Members have posted JP engine markings and numbers that have disproved what you 3 have been saying..  

 

I think your story may convince some people.... well 3 people anyway...   But to spin a theory like your spinning to a bunch of enthusiast's, some of which have vast knowledge on all things Holden, let alone Torana's,   will take some proof, not just the word of someone ...

 

So please no more words....  no more fools and there money type comments, no more ring CAMS (They are not pushing this theory, you are !)...   Just put up some proof to support your theory, or admit you have no proof, and it's just what you believe/want to be true....  

 

I'm starting to think,  if we, the non believers stop giving this topic air, it will simply fade away.....  because apart from here, there is no mention of this topic anywhere  else ? ......

Put a simple pole up, something like.

 

Given the lack of documentation to support the theory do you believe that only JP blocks with a second date

of a 3 cast on them, are the only genuine JPs to exsist ?

 

YES

or

NO

 

This pole would then be at the top of every page, IMO showing very little support for the theory.

It appears to me be a big attempt to get the stupid term "dual cast" to appear on Google searches. Hence why its important to have it contradicted in each thread it appears.

Who are the fab 3 in terms of XU1s?

Are they the heads of clubs?

What are their credentials?

Were they involved in trying to get extra cars into the 150 list?

Did they have a relationship to a particular member who hasnt been heard from in ages?

 

As an outsider they seem to be trying to prove something that by all accounts has been disproven.

All I am left with is the question as to why?
