289 vs 318 ..... Ford vs Mopar

My brother had a 65 Mustang coupe with a 289 in it. We pulled it apart and ordered the 271 hp rods and cam, 10.5:1 forged pistons, Offy intake and a 750 AVS from a 440 Plymouth. Man than thing was quick. 3.90 geared 9" Ford limited slip rear. He said he broke into the 12's with borrowed slicks. Only problem with that 289, was keeping a transmission behind it. He rolled the Mustang coming home one night. We never raced each other, both cars were very fast. I never raced my best friends 350 Camaro either. Never seemed important back then. That 289 is the only non Mopar engine in the basement today.
