How could the rings put in be wrong ? Holden did not know what they were doing ?

GMH didn’t do it, they didn’t have the capacity to rebuild 100’s of engines pronto. Read what I said again, I said nothing about installing rings wrong.

I said how could the rings put in be wrong, are they different to the auto 350, I don't see why they should be any different at all.

GMH had to get them rebuilt locally but the rings put in were wrong ? in what way are rings wrong.

Most died pretty quickly ? why, it sounds like rubbish to me and I never said they were installed wrong, you can put them in upside down but I never said that at all.

So molly rings were put in ? like in what you would put in a Falcon GT-HO.

It is fact, Whether you choose to believe it or not bothers me not. I wouldn’t type it if it wasn’t fact.. Go and research what bore finish is required for standard versus premium rings, and what happens if you use premium rings in a bore finished for standard cast rings.

No the guy was in Brisbane. Not sure how he came across the car but I think it was without driveline.

I never said I did not believe it.
Oh that's all it is, the finish of the bore to the ring type, by premium rings you mean molly top ring, that has to be bedded in correctly as well, driven hard as you can straight off the bat too make them bed in best.

No, I don't believe they were moly rings, after all this was the late 60s. I seem to remember a lot of drama with chrome rings vs cast iron rings.

Standard rings in a 253 or 308 starting in HT were Moly according to Engineering technical and also the Service Manuals. Same documents list Chrome rings as standard rings in 307, 327 and 350. Chrome is chrome plated face cast top ring, chrome steel oil rings and tapered cast iron on middle ring.

Standard replacement rings as listed in all HK, HT, HG and early HQ up to ADR26 engines (text from parts catalogues):

"Production" replacement rings for low mile and warranty work, part numbers listed are all moly ring sets.
"Service" replacement rings for high mile engines, part numbers listed are "Chromeflex" ring sets. I think the difference is the middle ring (will check)

The rings listed in the HK-HQ parts catalogue as "production" are listed in US parts catalogues as "premium" moly rings for high performance engines like the fuel injected 327. The boxes the rings come in state they are moly too.
