I ran a string of 10.70's on my 8 3/4 this year. Stock axles, stock caps stock gears and a stock cone sure grip. The car is 3400 race weight with exhaust on. HOWEVER I have a big squishy converter, and I think the 3.23 gears are saving the axles. Best 60' was a 1.55 buy most were 1.59-1.61. I plan on changing to a Dana 60 this winter. Here is a video of a 1.61 leave. It doesn't look like this set up will break anytime soon, but it's a boring launch.
