It has a "sleeper" look to it, Noel! Pretty cool!
My mother in law killed a slant 6 one time back in 1976! It was in a 1965 Valiant. Got a phone call from my then girlfriend at work to see if I could help. Boss let me go and a rod came out of the block and broke the starter off! MIL's brother showed up with a trailer soon after I got there so they got it out of McDonald's parking lot. I helped them shove it on the trailer and went back to work. Her brother put a different slant 6 in it and they drove it for years too!
I bought a 1966 Valiant from that guy a little over a year later and gave it to my then fiance' for high school graduation to use for a college car. it was a 2 door post, 3 on the tree with a 170 slant six. Yeah we were dating young and now we are old farts---LOL!
