To make matters worse... Or better- depending how you see things, I installed a full boogie 69 boss 302 and 4 speed. My car was one of the first 66 automatics and everywhere I took it, everyone said that aint a real SHELBY everyone knows they came with 4 speeds.
That did it in went the cool drivetrain and the rest is history. A rockin stereo for those times with your sweetie, or your rock and roll buddies, and the roar of Turbo mufflers with side exiting pipes to get your man groove on.
