I THINK IT GOES BACK TO THE 60's WHEN COBRA WAS BEATING THE VETT'S AT THE TRACKS. WE FORD LOVERS HAD A CAR THAT COULD BEAT GM. I LIKE VETTS BUT LOVE FORD. I WOULD NEVER PUT A 460 IN A VETT BODY!!!!!!!!! MAYBE A 350 IN A 32 FORD IS OK!! BUT NEVER A MOPAR OR GM IN A COBRA. AND IF I DID PUT A VIPER MOTOR IN A SNAKE BODY, I WOULD NOT TELL ANYONE!!!
