Does anyone know why Ford used a different motor mount design for Hipo vs standard 289 engines? This has always seemed odd to me. Were there failures with the standard mount on track cars? The need for a different ride-height in Hipo cars? Just curious.
1965 and, I believe 1966 through October/November had specific motor mounts. Personally, I don't believe they were stronger on race cars. Walt Hane, 1966 champ and race car builder/driver once told me that he always replaced the hipo motor mounts with standard ones on the cars he built for himself and others as they were better/stronger for racing. /Texas Swede
Thanks for chiming in TS. Thinking out loud, Ford may have changed the mount for Hipo exhaust manifold clearance.
