A couple of things on reading through this thread...

Kingsley Hibbard - he was an early Holden racer who retired for a few years. His return was in the Phase 3 days and he drove his car (probably that same yellow one) to Melbourne to run in the Sandown race. But he progressively pushed the envelope as he got closer and became the subject of a high speed police chase. He turned off the highway at Broadmeadow and tried to hide among the cars in the Ford car park but it didn't work.

That was as a Series Production car, the following year he turned it out as an Improved car as shown in the pics.

I always thought his body mods to the ex-Geoghegan Falcon were quite lacking in understanding of the stresses, and this is especially so seeing as the car had been given a good going over by John Joyce. So many mods were carried out that it carried a Bowin job number, I think it was the Bowin P7 but couldn't swear to that. It was in that form that it handled so well and it dominated the Oran Park ATCC round totally, with lap times previously unheard of.

But it wasn't only the handling, it was also the testing. Mick Lambert told me they spent a full day (or was it two days) at the circuit trying different things and in particular diff ratios. He couldn't believe it, they changed from one ratio to another, maybe it was 4.1:1 to 4.2:1, just a small change like that, and picked up over a second!

So what went wrong? The engine was cutting out in left hand corners, and there's a few of them at Oran Park. A comment was made that 'we always do a new wiring loom for all of our cars...' implying that something in the wiring loom, which they hadn't replaced, was amiss.

This was also the race where John Harvey really taunted Moffat. As Moffat came up to try to pass him after Jane had faltered, John would pull to the left of the straight and stick his hand out the window and wave him by. As he planted his boot into an engine that had much more grunt that Moffat could muster.
