Low comp motors are for standard fuel used by farmers etc.
engine capacity increases as car size increase, a 149 in an HQ would be very pushed for any decent accelleration or fuel economy.

To add to the above, when holden started bringing out its larger 6cyl motors, the motor racing industry was becoming more stringent - further requiring racers/race cars to have factory motors in their race cars. As this became a much larger fraternity, t

The 202 first appeared in the HQ, in July 71, the LJ came out in January 72.

Warren, did the 202 actually first appear in a HG commercial as a saleable vehicle (ie not prototype), or would it have been first in a HQ sedan/wagon/coupe??

The HG commercials fitted with 202 and 173 engines were produced during the HQ programme, as the utes and vans came on line later, a bit like the current Commodore ute and wagon are still VZ even though the sedan is a VE.
So once HQ production started

Your guess sounds about what I was thinking too ie build the HQ's ready for release, whereas the HG commercial production for that same period would have been a dribble. What I was getting at though was Holden must have been pumping out HQ's for at least |

HGs were still being produced to service orders when the HQ started pre production, but they would have still been fitted with 161/186 engines. Although we did find a late HG with a 186 engine with an adjustable rocker 202 head on it. This was a very inte

Thanks Warren. Just interested how it all works. I've been looking for a HG with a 173 or 202 for ages, just to say I've seen one. The only one I've found however is a very late HG Kingswood ute, but it is unfortunately a 253 3-speed.

There are two HG panel vans that a fellow I know has found over seas, they are a 4 seater and a 6 seater 3 door panel vans. He is trying to get them back here, but these would be good examples of very late vehicles. The company that added the third door w

Hi Warren,
You appear to be the guru, so maybe you can answer this question.
My LC GTR Torana (In same family since new) came out with a 173s motor AND an Opel 4-speed. My understanding is that the Opel 4-speeds had ceased (replaced by Aussie 4-spee

As far as I know the opel and 161S were replaced with the 173S and aussie 4 speed at the same time. So I think it should be a 173s with aussie, just check the gearbox again, if it has three rods on the shifter it is Aussie 4 speed, two rods is opel.

Hi Guys.
Unusual things happen in production. The 173S & Aussie 4-speed (Like the CK XU1 & Aussie 4-speed) were supposed to be introduced at the same time, but several 173S with Opels have been identified & there is a thread on the gmhtorana site at th |

The change over of XU1 is an interesting one, for many years I was chansing a 3000X engine with aussie box, 3.07:1 first, the 71 parts bok listed a couple of unique parts for them, before the CK engine became available, the later 71 book has the CK engine

Warren it's funny how people have always called the XU-1 M20 box an M21 6cyl - it's simply an M20 with a different cluster and input shaft! Holden did homologate 2 x 6cyl M21 boxes for the 1973 LJ XU-1 though. The more common one used the input shaft off |

Hi Warren.
I've never seen a CK XU1 with an Opel 4-speed, but I have seen a CF (173S) GTR with an Opel. The thing with Opel 4-speeds is that GM-H must have had them stockpiled. Accoring to parts & owners manuals the LHD Torana 6 cyl continued with the |
