All genuine JPs have a wiggly '5'. Well spotted Dave. My block was ridiculed by one of the 3 Amigos for having a 5 bent like a banana. Turns out he was totally wrong. Funny that, thanks for the clear research.

Sorry to correct you Keith but your block was ridiculed because it did not have the 'BANANA' like bend in the horizontal bar atop the 5.

Your 5 clearly has this bend like all other genuine GMH stampings.

I wonder who the real Wanker is now that can't spot a real stamping from a fake?

Not just JP prefixed 202's Keith. Just about everything cast iron (that I've seen in any case) out of the Fisherman's bend engine plant or even stamped at the assembly plants (like SBC's were from the start of 1968). Even the Nasco/GMP&A stampings appear to use the same font stamps. They must have been a standard supply set from whomever was GMH's tool supplier, someone like Bennet and Wood or Repco or whomever they were sourced from.

 

Here is what a Flint van Slyk road engine plant stamping tool looked like. By the suffix this is about 1992. Different font.

That is probably where it comes from. There are a lot of variations in what characters were used in SBC's too, and it is great as it allows you to quickly spot a real engine, eg the use of O instead of 0 in the above example. There are a few of these too in GMH, but unfortunately not as many as GM had.

Bad picture, don't know any ex race cars. You guys think you are the experts, we'll see what you think. I'm am not getting dragged into your delusions and games and BS in general.

 

NOT ALL 150 LIST ENGINES ARE DOUBLE DATE CODED. I'll keep typing it until the cows come home.

This is a very interesting thread. I'm considering getting into document examination (passports etc). Never thought of engine number examination. Surely the best way to spot a fake is to study the original and all of its characteristics. it might be better to study blocks that are worth bugger all, very unlikely to be fake, and then compare with the JP stamping. Might start looking closely at all my blocks.

Regards

Hmmm, no shouts of FAKE FAKE from the clowns that always appears whenever something that doesn't fit into their little theory of the world appears. Have they been banned again?

Hi Jon, was suggested by another member that has a fair few old 202's laying around, and agree, will start to compile stats on these, which should be a good indication for the more desirable blocks.... :)

if anyone does have any spare holden 6's cast between 69-75 laying around, please add pics of the following:

 

- Clear pic of the engine number taken from directly above... preferably with all paint removed from the pad.

- Clear pic of the cast date, clock and mould numbers.

 

Thanks.

Glancing through Torana Tough last night and noticed that JP389335, which is not a 150 listed engine, is also not included in the list of additional JP engine numbers found to date (engines whose numbers fall within the gaps on the 150 list) that have been identified as also having 9/2e internals. This engine is also claimed to have the dual cast date.

Considering the 1973 XU1 this engine belongs to is featured in Torana Tough and the fact this engine is touted as having the 9/2e bits ex factory, I'm surprised it was not added to the list of 11 additional numbers.

And some of those 11 engines listed don't actually exist yet have been claimed to have been found....

So, you have 6 of 11 on record, what about the other 5? Byron didn't claim all 11, only some of them.

BS Crabba. The list of engines were given to Norm primarily by Bruce and/or Mike, and then some pruned off by yourself which my guess is why JP389335 isn't included. Don't worry, it'll be all made public eventually and Norm will be involved in that.

 

Tell me which ones you've actually recorded, and i'll tell you which ones you are lying about.
