HR is my favourite car and was my first
I had a HR x2, those twin Strombergs were a pain in the arse to tune together.
Time I finished it had triple su carbs and a 7/8th Bathurst race cam, basically a hot xu1 motor, lots of heel toe to keep it idling at traffic lights and had the most amazing exhaust bark I have ever heard, still the fastest car I have ever driven.
It had a set of tramp rods as well. One day going a bit fast with a few people in the back around a steep corner one decided to dig it the road, the most violent moment in a car I have had, in a split second we were facing the other way going WTF just happened.
Another time cruising along my rear wheel with the axel still attached decided to over take me, pulled off all the brakes hoses which causes me to have no brakes, I was lucky to have the tramp rods that day for it to grind away on the road.
It ended up towing caravans in smash up derbys
Its one car I really miss and plan to buy another one day
