The '66 Tri-Power is said to be the best of any year. Therefore, the '66 Tri-Power GTO's ran quite well.

The Knafel '66 Tri-Power GTO car, which I call the "Trophy Car", MAY have been the winningest '66 GTO ever. Don't know. Knafel actually ran at least 2 of these cars that looked similar. One had a lighter colored bottom, with a darker colored top, the other with a darker bottom & lighter top. Don't know if they ran identical set-ups, or not. They did haul 'em on the same rig, as a couple of the pics below depict.

Royal Pontiac also fielded at least one of the '66 Goats. Once again, I assume that many Pontiac dealers, across the country, also fielded, or at least sponsored a '66 GTO.

Don't know when the last competitive '66 Tri-Power GTO was active. Anybody know ?

One of the best is pictured here.The CT. car of Gaudreau and Kovitch. Bob dominated the class at Indy , only to be tossed for a suspension violation, bringing in arch rival Loyed Woodland... 12.50's was damn fast at that time.
