289 vs 318 ..... Ford vs Mopar
Back in in SW Ga 1966-67 I went to a Jr college. There was a kid there that was a legend, had a 64? Mustang coupe, 289 4 speed, shifted by ear. Ran for $100. Lot of money back then. Seldom ever lost to anything.
He swore it was stock, but word was it had lots of Shelby influence.
It was a suitcase college and everyone went home on weekends. He had his mechanic tune it every trip home! I had seen him drive it 150 mi. for a race.
