A co-worker bought a 180 HP turbocharged version a number of years after it was made and couldn't believe how much power it had when the turbocharger was near full boost.

He had it over 110 mph when a fan belt blew up. I'm not sure it hurt the engine but I think the belt took out the power steering. Made a big noise,too.

Seems the original belt was extremely solid construction, but regular mechanics tended to replace it with standard items from their favorite auto parts store.

The turbocharged version of 1965 was doomed by emmission controls that were just coming in that year, but Nader crusade did a lot of damage too.
