Comparison 340 / 289

In 1984 I changed high schools.The "BIG DOG" at my new school had a '66 fastback Mustang,289 4spd,4bb"doublepumper",headers.
He was always trying to get me to race him in my '66 cuda,273 2bb auto single exaust.
One night he pulled up next to me at the traffic light in front of the local hangout and yelled THAT IS THE BIGGEST SUPIDEST BACK WINDOW I EVER SAW!!!I said 'it'll look smaller in a second". it did,and he never spoke to me
again!!
