Ron France sent me this picture of his 68 Camaro that he owned around  86-87. 350 SB , 4 speed , 5.13:1 rear.
Best he managed was 11.88@122mph, after all, he did have to drive it home to Bournemouth when the day was over!
In the background you can see Brian Patemans Firebird , always a strong 10 sec street car.
