HA special saloons update
Back in Late 2008 and in 2010 I wrote about three versions of the Viva HA saloon, the Ian walker race car, the Lawrence Tune GT and the Brabham Viva GT. Below are links to those articles.
After a while one does feel the need to update those, with more found adverts on the internet and articles written in magazines, especially as Andrew is asking. Andrew is the owner of the only known survivor of the Jack Brabham HA GT.
So here we go starting with the Ian Walker Sprint, and for the first time I see the mention of the consultant engineer being no less than Bill Blydenstein.
Next an Article from Motor dated April 1964, which shows a better image of the exhaust on the Lawrence Tune GT. It notes the 1/4 mile time now below 20 seconds which is good as the later HB saloons I have raced never seem to get below that magic number even with a bigger engine. I also note it mentions Shaw and Kilburn, and who this is a NON vauxhall supported car.
Next is an advert for the Brabham GT,
the last item here is a new, but hardly unexpected name Bill Blydenstein, in this article note the 1180cc version of the engine and a stroked 1280cc version! This may of been and early 1159cc engine over-bored and the later 1280cc a stroked 1159cc (as the 1256cc engine was not released until the early 1970’s). All of this work laid the foundations of the more commonly known HB Brabham for which people still fight stupidly over to this day as some sort of super car and unknowingly think was Mr Blydenstein’s first Viva special.
