I’m getting old

Not A-body related but I was at the dragstrip with my "65 hemi Coronet and the hood was off. A kid with a late model Mustang was pitted next to me. He walked over, took peek in the engine compartment and asked "is that a big block Chevy?" I was stunned.
When I was in my early 20`s I had a 53 Ford truck, a friend looked at my engine and said "man that thing`s got a Hemi" lol
