I haven’t seen a slant 6 sewing machine, lol, in quite a while. No offense intended. It reminds me of my aunt. She had one in her duster. She bought it new in ‘73. She only bought it because someone stole and stripped the ‘66 coronet that my dad painted and sold her. Plum crazy with white top, white/charcoal interior, buckets, console, chrome shifter, 383 4 barrel... loved that car. Anyways, we put three engines in the duster. When we returned the cores to the salvage yard, there was a pile of them, all with number three rod broke or hanging out of the oil pan. Apparently they had a manufacturing defect in that era. I used to joke with her about it sounding like a sewing machine, but it would really wind up and go. A funny side story to the plum crazy paint: my dad used to own a body shop and repaired cars for all of the used car lots back in the day before auto auctions. Anyways, he had just painted a Malibu white prior to painting the coronet. Even though the coronet was painted in a spray booth, somehow some overspray tainted the white Malibu to give it a pinkish tint, lol... well, in those days it was acrylic enamel. Once it was sprayed, it had to cure 30 days before doing anything with it, so there really wasn’t a quick fix. I remember my dad delivering the Malibu at night and blaming the tint on the street lights... he was a hard worker, but hustled in more ways than one! Sorry for the long reply, memories.
