I wouldnt worry about the clutch, he would dump it on slicks from 3500rpm and he was putting down almost 500rwhp and somewhere near there tq wise.

Id definitely do the 6.0 first though.

12.58 @ 109 actually.

A friend borrowed my slicks and went a 10.0's in the 1/8thbone stock 4.8 5 speed with a mild tune.
