I also wonder why only 2 so-so pictures and almost no information. Does the seller know nothing about cars, are they being coy or are they just trying to get you to call for the spiel? Perhaps they are just impatient or were rushed. I'm going to assume 283 Powerglide. Who knows, maybe it's a 427 TH400, it is all badged the same externally.
I always liked red 67 2+2 convertibles since they were new.
