matching up engine number

[wbute]

Torana motor will have wrong engine number prefix as will early Commodore.
The only one that suits HJ is a QT motor in 308 or a replacement Nasco block with NT prefix.
11QT is HQ to HZ Statesman. It was a favourite way of re-birthing a stolen 308 as well. Just add 11.
Chasing the date code doesn't really mean much though. The only authentic engine number is the one on the purchase documents.
All HQ to early HZ 308 were the same prefix regardless of model or series except Statesman. It was only a replacement block that got a different prefix. Torana and Commodore were a different prefix as was WB. L34 were different again.
So you want QT for 308 or QR for 253.
