Yes, you've found the car.
I think 'Extreme Machine' is just a description and is not meant to be its name.
In fact I can't see that is has a name, which is why I didn't ask for one!
The fact is it's a scratch-built car from 1964 powered by a 1779 cc VW engine with a 2 barrel Holley built by a restorer of vintage aircraft, so you get the point! It actually said on the site that it was influenced by Can-Am style cars, but did they exist as early as 1964? I'd have to check that..
Well done.
Edit:
The first Can-Am season was in 1966, so either this car is based on a 1964 car rather than being built then or it's not inspired by Can-Am cars as it claims to be!
