Engine install on assembly line

Yeah your right , I’m going with is a 273 Hopi for sure . Anybody’s guess on likely swap on motor. I still feel ok on my $7500 buy on an almost no rust and a good complete car less exhaust and radio 4speed car. One of these was my first car in 1972 at the age of 15 and my wife found this one and had it here from cali to ky for my birthday just a few weeks ago!!!!
