In 1966 I had a Pontiac Tempest with a 6 cylinder engine with an overhead camshaft.Does anybody have info?

I am desperately trying to find a car that Pontiac made with this engine. It was a screamer,to say the least.It would do close to 10,000 rpm. It didn't have a lot of low end torque, but wind it up and watch it go! I've asked a lot of people who love cars & nobody believes me that Pontiac made this engine. HELP!
