A friend let me borrow the book quoted below and I'm curious about the quote...
From "Shelby's Wildlife: The Cobras and Mustangs" by Wallace A. Wyss, 1977, p 46:
"Shelby-American employees used to get a kick out of the test results reported in magazines. In a September 1963 test Motor Trend reported it used a 7200 rpm redline. While he doesn't remember specifically, Phil Remington suspects the Motor Trend test car might have had a helper kit (roller tappets) "because the stock engine wouldn't hold together much past 6500 rpm."
Any comments?
