Its spelt Vizard . Dave was around in my era. I lived through its development & owned them in all states of Tune. Above 80 they started to struggle & any thing much over 100 was really going for it .
A change to a 2.9 & a Jack Knight box helped but it then lost its road squirtability. Any cooking 1.6 today would be far too quick for an 'A' series motor at stage 2. I prefer to remember them scrabbling for grip tearing past Riley 1.5's & modded Anglias back in the day. I love them but they are like me relics from a bygone era & past it .
