Yeah, I seem to remember a Pontiac powered ride, similar to that one. This was one of the 1st Pontiac powered cars I ever rode in. It had a 389 with an old "Hydro" trans. We named it "The Blob" after a ridiculous spook movie, by the same name, about a big blob of jello or liver lookin stuff that ate people.
The car belonged to one of my schoolmates, who we nicknamed "Howard", after some geeky TV character at the time. Some of us guys would load up in The Blob and cruise the streets of our local town, on Sat nights. Howard's older brother also had a 4-speed '65 GTO. So, Howard borrowed the GTO one time and took us guys for a "spin". Yeah, it was great, and I was hooked. Had to have my own 4-speed Goat.
The Blob never got a 455, but Howard's current ride did.
