Back in 1971, my future mother-in-law had a 1968 Impala station wagon with a 327. My future wife (girlfriend at the time) was showing off and laid some rubber in the high school parking lot. The defective motor mount broke and allowed the engine to lift up and jam the throttle linkage wide open. Before she could turn off the ignition switch, she ended up hitting a cement curb, buckling the right front wheel. Nobody was hurt. It turns out there was a massive GM recall on motor mounts for many 1968 GM cars with V-8 engines. The Chevy dealer replaced the damaged wheel and suspension (at no charge) along with installing the improved motor mounts.
Good story. Glad to hear Chevy made good on the repairs. My dad had a '68 Impala and I remember the recall. He did the recall. I currently have a '68 convertible and have checked to see that the recall was performed and it has been.
Had a 68 Caprice station wagon w/ the 396, 325hp & changed it up w/ a 427 hi per cylinder heads, w/ a 427, 425hp cam & installed headers & it ran great !
All of those wonderful safety features featured on this 1968 Chevrolet were featured on EVERY 1968 General Motors car. Amazing what government mandated safety requirements will lead to.
