Engine Stamps - what should they be?

[Dr Terry]

Not correct.

VR prefix is 4.2 V8 Commodore.

WR is 4.2 V8 WB commercial

QR & ZR are HQ-HZ Holden 253/4.2 V8 prefixes.

That's what he said.

QR = HQ to HZ

QR = HQ to HZ

That's clearer. Ta

The reason for my question is VR is for VB Commodore which was released 9/78 at the same time as this HZ Sandman (10/78). I was wondering if they had changed the engine stamp by this stage?
