That max'd out thermometer reminds me of a colleauge who had a Moggie 1000 van.
He'd extensively worked on it with a completely rebuilt and bored engine, stage 3 head, the works.
When anyone asked him how fast it went he just said "Smiths"
Confused ?
Nope, the speedo went from 0 to 60 then Smiths at the bottom which he easily achieved
