During the SS&DI magazine test back in 1969, Ed Hedrick used 3 clamps per side on the Yenko Camaro demo car. Car got into the 11's.

BTW, Ed is an engineer, who helped Grumpy with much of his chassis/driveline problems. At the SCR Ed spoke about the time Grump watched as Ed launched Grump's car several times "inside" the shop.

A little off the main topic, but I also found it interesting when Ed was talking about the natural frequency (vibration) of the driveshaft and what engine rpm it happens at...
