That is the make & model of the first 426 Hemi-powered car that I ever laid eyes on back in the day: A black HP2 monster with a 4-speed. It was definitely no slouch back then.
The first “muscle car” I remember seeing?.....hmmm. My dad and mom and I came back to the states after two years in London. My mom and I (I was 15, no license yet) were driving to New Mexico for my dad’s next post. We stopped in my mom’s hometown in nfw Pennsylvania. Not a MOPAR, but at the Ford dealer in that small boondocks town was a 63 1/2 galaxie 500 fastback. Black on black buckets 427 dual quad 4 spd. Yeah, I liked it. 😀
