LS3 Engine Number

[Wazza]

I had the number as shown in the picture on my crate motor from the States..
( The LS7)...

Cops told me that it was not a number I could use in Australia, and they issued an engine number that then had to be stamped on the blank area on the engine.( I seem to remember that this "Blank pad" was on the front right...i.e. "Australian"drivers side of the engine ??..not sure)

They said those numbers that were already on the engine can't be used as engine numbers, because they had the letter Q amongst the letters and numbers...and this can be misread as a Zero ??...something like that...

In any case, they made it clear that those numbers ( as circled in that photo) are some sort of casting I/D number...or a serial number that the manufacturer uses in their system....not an Australian engine number.

Hope that helps.

Cheers,
Warren
