Wow, I seem to be resurrecting a 10 year old thread here, but some websearching on triple SUs led me here. So i just signed up to the forum from the UK to comment and try and research my car.
@deadflo, I know the car you referred to because i have a copy of that Z Car Magazine article. I own another triple SU car mentioned in the same article, not the yellow one in British Colombia, but a red one built by a friend of the yellow car owner. My car, the red one, later found it's way from BC to Texas in the 2000s, making me wonder if that owner was the unnamed person referred to by kmack. I know that owners id too, as the car was featured in a Z Club of Texas mag which i also have copy of.
I bought the car last year, and have made contact with the BC owner/engine builder which has helped me to in some of the cars history. But there is more to track down if its Texas years before it came to the UK for new. only last weekend i took it to Japfest at Silverstone racetrack.
