he ran a 10.32 in 1970 with it, but it tore itself apart from the violent launches as it wasn't braced well enough to last long, and it wasn't competitive against the smaller Comets and Mavericks that followed
Ford did commission two 1969 Mercury Cougars with the BOSS 429 engine, and sold both of them for $1 a piece to “Dyno Don” Nicholson and “Fast Eddie” Schartman. Designated by Mercury as “clinic cars,” the two BOSS 429 Cougars toured through dealerships teaching Ford gearheads all about horsepower.
Dyno Don immediately ditched the 429 engine, replacing it with the even rarer 427 Ford SOHC “Cammer” engine and he painted his car red. Fast Eddie kept the 429 engine and the white hue, but converted his Cougar over to a 1970 hood and front clip. Both of these cars had fiberglass front panels, which technically disqualified them from running in Super Stock.
However, the cars were reportedly so slow that nobody really seemed bothered, and they were hardly raced anyway. Both Cougars were supposed to be returned to Ford, and in all likelihood were destined for the crusher. Curiously, neither car was returned to Ford, and the Cougars disappeared.
Fast Eddie’s car was sold in 1971 to Lou Cerra, who replaced the engine and raced it through 1973. It was then sold to Steve Comstock, who dropped a 454ci Holmann & Moody BOSS engine into it. It was raced for a few years before the body was twisted something fierce. These Cougars, despite being built for racing, lacked many important features like sub-frame connectors or a real roll cage (a bolt-in kit was used instead). It sat around unloved for awhile before being bought by Douglas Herzog, a racing engine builder and 429 aficionado.
