Broach marks. Or the block was blank and restamp but the casting date would be wrong.
I have seen a blank block no engine number and has broach marks. Cheers Jason

I did post the same engine number a few months back but the image was too blurred to convince people one way or another. So with new phone and camera l can now get a clear pic posted and guess what??? Nothing changes. Restamp the doubters say. Post a pic of your engine number boys and

Don't worry about x-raying Keith's, as it is not in doubt.... we have been through this before.... The 150 list is well documented, the Dual Cast issue is not..... so I say let them prove their dual cast motors are legit..... I for one would like to see Anthony's SVO engine number ..... Why he put someone elses number up to prove his point is beyond me..... put your own up and let us see how legit your number looks..........

Great Thread Skap, and thanks for showing us what we should be looking for when it comes to JP's .. Just checked mine, and feel way more comfortable now

Post a pic mate

Ian,If you or anyone else wants to see my stamping/block and the number 3 on the left hand side it will be on display at Geelong all Holden day next Saturday and Phillip Island in two weeks time on the Sunday......................About the photo,s of the dual cast block 7H3 JP 397 the owner did not know how to put photo,s up and wasn't happy about Byron comment that all dual cast block had there engine numbers painted thats the reason if i have someone,s photo,s or parts i always ask for permission the photo of keith's engine number was send to my via email on 12 November 2015 and asked my opinion.

Cheers

Just so we are clear.... You 3 propose that ALL 150 list engines are dual cast, and further that ALL 150 list engines are a number 3 Mould ?

Only asking because you seem to be the driver behind the Dual Cast Topic... and you are quite capable of posting pics... so just wondering your reluctence to posting a pic of your stamping pad... cover some numbers if you want...

It was nice of your friend to allow you to show his number pad, but he is not the one making the claims on here ..

As are owners of known original single cast date 150 list JP engines or JP engines with a core pattern number other than a 3 not happy with your assertions that their engine blocks are all restamps!

To my knowledge there is no such documentation in existence. The presumption is based on anecdotal evidence and I suspect that any JP block that has a core pattern number other than a 3 has been automatically dismissed as a fake as it does not fit the biased body of evidence..

How were these engine numbers stamped on the pad, individually, in a jig or in a press ?

Of the listed 150 1973 Bathurst engines, there could be only as few as 950 remaining........
