Concerning Engine Serial Numbers

[SteveJ]

Did they just get rid of the L for the S130's? Looks like they had it for the S30's.

Per the link I posted, yes.

Also, here: Black Dragon Automotive - Parts & Accessories for Datsun 240Z, 260Z, 280Z, 280ZX & Mazda RX7

Ingenious. By just adding the '1' they could use the same codes for the cars, without having to come up with a whole new system until the 300ZX came out, which was a totally different car.

I'd assume the 'L' in HLS30 was for the engine type (L series engine?) what do you think the 'H' was for?

This is all well-known and clearly outlined info (ever check the FSM?). H means L24 (240Z) or L28 (280Z) and L means LHD (R is for RHD).

Looking back, Steve's post RIGHT before yours has a clear description from Black Dragon...
