It was a bad time in my driving "career"
The car itself was known by the local constabulary and as such I was constantly harassed.
It was slightly modified when I had it.
I rebuilt the engine, it had a high compression ratio (about 12 or 13:1 IIRC) and I was running it on aviation fuel (higher octane rating).
It also had lowered suspension.......lower than the legal requirement at the time.
Close ratio 5 speed gearbox, and a locked differential (not limited slip.....locked) which had a 4.4 ratio.
I ran 245 width tyres on the rear which filled the wheel wells perfectly.
This meant it didn't have a really high top speed, but was a killer with acceleration
It was pretty quick for an old car.........but wouldn't stand up to decent modern performance cars now.
Sometimes I regret that I sold it.
